android 定制


Launcher 總結:



1、launcher的布局太居中,要想兩邊拉伸

<\packages\apps\Launcher2\res\values\dimens.xml>

    <dimen name="  apps_customize_pageLayoutPaddingLeft">40dp</dimen>

    <dimen name="  apps_customize_pageLayoutPaddingRight">40dp</dimen>

apps tab欄的寬度( Launcher2 icon 數目、大小)

\packages\apps\Launcher2\res\layout-sw720dp\workspace.xml>

    launcher:cellCountX="10"
    launcher:cellCountY="6"



2、或者不想改數目:

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizeTabHost.java>

    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

          mTabs.getLayoutParams().width = contentWidth   + 108;



3、workspace、AppsCustomize的cell大小:

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>

    <dimen name="workspace_cell_width">110dip</dimen>
    <dimen name="workspace_cell_height">110dip</dimen>



    <dimen name="apps_customize_cell_width">110dp</dimen>
    <dimen name="apps_customize_cell_height">110dp</dimen>




4、裡面icon的大小:

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>

     <dimen name="app_icon_size">80dp</dimen>



5、workspace沒有拖動,第二頁第一個icon出現在第一頁的最右邊:

加大workspace的寬度,或間距:

workspace的paddingLeft、paddingRight:

<\packages\apps\Launcher2\res\values-sw600dp-land\dimens.xml>

    <dimen name="workspace_left_padding">50dip</dimen>
    <dimen name="workspace_right_padding">50dip</dimen>



workspace兩屏間距:

<dimen name="workspace_page_spacing">100dp</dimen>



修改workspace的字體大小:

如果沒有就添加:

<\packages\apps\Launcher2\res\values-sw480dp\styles.xml>

    <style name="WorkspaceIcon.Landscape">

        <item name="android:textSize">13sp</item>

    </style>



6、加wallpaper:

1.<\packages\apps\Launcher2\res\values-sw600dp\wallpapers.xml>

   加wallpaper的名字

2.<\packages\apps\Launcher2\res\drawable-nodpi>

   加如wallpaper



7、gallery的widget默認添加到workspace上:

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

    <!-- Middle screen [2] -->
    <appwidget
        launcher:packageName="com.android.gallery3d"
        launcher:className="com.android.gallery3d.gadget.PhotoAppWidgetProvider"
        launcher:screen="2"
        launcher:x="1"
        launcher:y="0"
        launcher:spanX="3"
        launcher:spanY="3" />



<\packages\apps\Gallery2\src\com\android\gallery3d\gadget\PhotoAppWidgetProvider.java>

    @Override
    public void onUpdate(Context context, 
            for (int id : appWidgetIds) {
                if(id == 2){

                    helper.setWidget(id,WidgetDatabaseHelper.TYPE_SHUFFLE, null);                 
                }
       
    }



8、在桌面上添加網頁的快捷方式:

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

    <shortcut

        launcher:title="@string/application_name"
        launcher:icon="@drawable/ic_no_applications"
        launcher:uri="http://www.aaa.com"
        launcher:screen="0"
        launcher:x="0"
        launcher:y="3" />



9、在桌面上默認放文件夾:

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

     <folder
          launcher:screen="2"
          launcher:x="2"
          launcher:y="2"
          launcher:title = "@string/application_name" >
        
        
     <favorite
          launcher:className="com.android.deskclock.DeskClock"
          launcher:packageName="com.android.deskclock"
          launcher:container="1"
          launcher:x="0"
          launcher:y="0" />

     <favorite
          launcher:className="com.android.calculator2.Calculator"
          launcher:packageName="com.android.calculator2"
          launcher:container="1"
          launcher:x="0"
          launcher:y="0" />
   
     </folder>   



10、桌面上添加快捷方式,點擊播放視頻:

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

<shortcut launcher:title="@string/application_name"

launcher:icon="@drawable/ic_launcher_application"

launcher:uri="file:///mnt/sdcard/external_sdcard/1...playermenu;end"

launcher:screen="2"

   launcher:x="1"

launcher:y="1" />



11、安裝apk,顯示隱藏的google play:

1.寫google顯示的apk:

GooglePlayShow的activity:

        ComponentName componentname = new ComponentName("com.android.vending", "com.android.vending.AssetBrowserActivity");
        packagemanager.setComponentEnabledSetting(componentname, 1, 1);
        
        componentname = new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity");
        packagemanager.setComponentEnabledSetting(componentname, 2, 1);



2.<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

            } else if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {
                if (!replacing) {
                         if(packageName.equals("com.example.googleplayshow")){
                              context.startActivity(new Intent().setComponent(new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity")).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
                         }
                    op = PackageUpdatedTask.OP_ADD;
                } else {
                    op = PackageUpdatedTask.OP_UPDATE;
                }
            }



隱藏google search:

<\packages\apps\Launcher2\src\com\android\launcher2\Launcher.java>

    private void setupViews() {

        mSearchDropTargetBar = (SearchDropTargetBar) mDragLayer.findViewById(R.id.qsb_bar);
        mSearchDropTargetBar.hideSearchBar(false);



    void showWorkspace(boolean animated, Runnable onCompleteRunnable) {

        //mSearchDropTargetBar.showSearchBar(wasInSpringLoadedMode);



12、widget中隱藏google play:

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>

updatePackages裡面添加:

if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){

    mWidgets.add(widget);

}



13、clock的widget下部分顯示不全,向上調

<\packages\amlogic\Launcher2\res\values\dimens.xml>

<dimen name="app_widget_preview_padding_top">10dp</dimen>



修改widget的text的size:

<\packages\amlogic\Launcher2\res\layout\apps_customize_widget.xml>

  <TextView xmlns:android="http://schemas.android.com/apk/res/android"

     android:id="@+id/widget_name"

     android:textSize="20sp" />



14、launcher中隱藏一個app:

需要該app的packageName,例如要隱藏settings:

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

        private void loadAllAppsByBatch() {

                    apps = packageManager.queryIntentActivities(mainIntent, 0);



                    ResolveInfo removeApp = null;

                    for(ResolveInfo info:apps){

                        if(info.activityInfo.packageName.equals("com.android.settings")){

                                removeApp = info;

                        }



                    }



                    if(removeApp != null){

                        apps.remove(removeApp);

                    }



15、launcher中隱藏多個app: 紅色為改動部分

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

      private void loadAllAppsByBatch() { 

   final PackageManager packageManager = mContext.getPackageManager();

            List<ResolveInfo> apps = new ArrayList<ResolveInfo>();

            List<ResolveInfo> allApps = null;





            int N = Integer.MAX_VALUE;



            int startIndex;

            int i=0;

            int batchSize = -1;

            while (i < N && !mStopped) {

                if (i == 0) {

                    mAllAppsList.clear();

                    final long qiaTime = DEBUG_LOADERS ? SystemClock.uptimeMillis() : 0;



                    allApps = packageManager.queryIntentActivities(mainIntent, 0);

                    for(ResolveInfo info : allApps){

                        if(info.activityInfo != null

                                && !info.activityInfo.packageName.equalsIgnoreCase("com.android.email")

                                && !info.activityInfo.packageName.equalsIgnoreCase("com.android.providers.downloads.ui")

                                && !info.activityInfo.packageName.equalsIgnoreCase("com.adobe.flashplayer")){

                            apps.add(info);

                        }

                    }




settings 問題總結:

1.入口,設置分屏顯示

frameworks\base\core\res\res\values\bools.xml 下的 preferences_prefer_dual_pane 為true.

<bool name="preferences_prefer_dual_pane">true</bool>



2.top level headers--這裡可以去掉左邊的headers

<settings.java>

private void updateHeaderList(List<Header> target) {

if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {
   target.remove(header);
}



3.默認字體:

public void readFontSizePreference(ListPreference pref) {

     ActivityManagerNative.getDefault().getConfiguration()



系統的Configuration是從ActivityManagerService設置的:



<\frameworks\base\services\java\com\android\server\am\ActivityManagerService.java>

mConfiguration.setToDefaults();

fontScale = Float.parseFloat(SystemProperties.get("ro.fontScale","1"));



4.settings的theme:

<\packages\apps\Settings\AndroidManifest.xml>

    <application android:label="@string/settings_label"
            android:icon="@mipmap/ic_launcher_settings"
            android:taskAffinity=""
            android:theme="@android :style/Theme.Holo"
            android:uiOptions="splitActionBarWhenNarrow"
            android:hardwareAccelerated="true">



<\frameworks\base\core\res\res\values\themes.xml>

<style name="Theme.Holo">

字體顏色

<item name="textColorPrimary">@android :color/primary_text_holo_dark</item>

加亮框的顏色:

<item name="activatedBackgroundIndicator">@android :drawable/activated_background_holo_dark</item>

觸摸框的顏色:

<item name="listChoiceBackgroundIndicator">@android :drawable/list_selector_holo_dark</item>

左邊背景:

<item name="windowBackground">@android :drawable/screen_background_selector_dark</item>

右邊的背景:

<item name="detailsElementBackground">@android :drawable/panel_bg_holo_dark</item>
title的背景:

<item name="actionBarStyle">@android :style/Widget.Holo.ActionBar</item>



5.設置--》開發者選項--修改後台進程限制



frameworks/base/services/java/com/android/server$ vi ./am/ActivityManagerService.java

大概839行 把int mProcessLimitOverride = -1;改成4(不得超過4個進程)

標准限制 對應 -1

不允許後台進程 對應 0

不得超過1個進程 對應 1

不得超過2個進程  對應 2

不得超過3個進程 對應 3



6. 默認不要鎖屏,設置-安全--屏幕鎖定 (無)

overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

<bool name="def_lockscreen_disabled">true</bool>



7. 位置服務--- 默認Google的位置服務為勾選

overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

<string name="def_location_providers_allowed" translatable="false">gps</string>

改成

<string name="def_location_providers_allowed" translatable="false">gps,network</string>

常用修改
一. 修改默認(Settting.apk 中選項默認值一般存在於 frameworks\base\packages\SettingsProvider\res\values\defaults.xml)
1. 默認勾選 未知來源
<bool name="def_install_non_market_apps">false</bool>

2. 默認鈴聲, 通知, 鬧鐘 音樂
可以在system.prop 分別配置

ro.config.ringtone=Playa.ogg (默認鈴聲設置,文件在/system/media/audio/ringtones 把喜歡的鈴聲放這裡,比如123.MP3放入ringtones文件夾中,這裡代碼改為ro.config.ringtone=123.mp3)

ro.config.notification_sound=regulus.ogg (默認提示音,文件在/system/media/audio/notifications 修改方法同上)

ro.config.alarm_alert=Alarm_Beep_03.ogg (默認鬧鈴,文件在/system/media/audio/alarms 修改方法同上)

3. 壁紙不跟隨滑動
packages/apps/Launcher2/./src/com/android/launcher2/Workspace.java  大概 875行
private float wallpaperOffsetForCurrentScroll()
修改 wallpaperOffsetForCurrentScroll 的返回值。 改成 return  0.5f;

二.隱藏或刪除某項
1.去掉設置中Wifi選項
device/amlogic/xxxref/xxxref.mk 文件中
# Device specific system feature description
PRODUCT_COPY_FILES += \
$(LOCAL_PATH)/tablet_core_hardware.xml:system/etc/permissions/tablet_core_hardware.xml \
frameworks/native/data/etc/android.hardware.wifi.xml:system/etc/permissions/android.hardware.wifi.xml \ (刪除)

2.去掉設置中藍牙選項
參考 wifi。
在 tablet_core_hardware.xml  刪除 <feature name="android.hardware.bluetooth" />    這一行

3. HDMI 部分
1)去掉HDMI選項  在system.prop中 加入 ro.hdmi.autoswitch=false
2)去掉480p 選項 在prop中設置 ro.hdmi480p.enable=false

4. 去掉 powerwidget 中 某一項
以去掉 gps 為例

在 packages\apps\Settings\res\layout\widget.xml 下, 移除

<ImageView

        android:layout_width="1dip"

        android:layout_height="match_parent"

        android:background="@drawable/appwidget_settings_divider_holo"

        android:contentDescription="@null"

        />



    <LinearLayout

        android:id="@+id/btn_bluetooth"

        android:layout_width="0dip"

        android:layout_weight="1"

        android:layout_height="match_parent"

        android:paddingTop="12dp"

        android:background="@drawable/appwidget_button_center"

        android:clickable="true"

        android:focusable="true"

        android:orientation="vertical">



        <ImageView

            android:id="@+id/img_bluetooth"

            android:layout_width="match_parent"

            android:layout_height="0dip"

            android:layout_weight="1"

            android:scaleType="center"

            android:contentDescription="@null"

            />



        <ImageView

            android:id="@+id/ind_bluetooth"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:scaleType="fitXY"

            android:contentDescription="@null"

            />



    </LinearLayout>

然後 com.android.settings.widget.SettingsAppWidgetProvider.java
注釋 views.setOnClickPendingIntent(R.id.btn_gps, getLaunchPendingIntent(context, BUTTON_GPS)); 這一行。

5.  去掉 Setting widget 中 某一項
以去掉 "網絡共享與便攜式熱點" 為例
根據"網絡共享與便攜式熱點" 這個關鍵詞 在 values-zh_rCN 中搜索 到的 key值, 然後在AndroidManifest.xml 搜索這個 key值。 找到對於的Activity 配置
移除 <category android:name="com.android.settings.SHORTCUT" />  這一行。




6. 修改浏覽器默認浏覽器模式

packages\apps\Browser\res\xml-sw600dp\advanced_preferences.xml

<ListPreference

       android:key="user_agent"

       android:title="@string/pref_development_uastring"

       android:entries="@array/pref_development_ua_choices"

       android:entryValues="@array/pref_development_ua_values"

       android:defaultValue="3"/>

   修改 android:defaultValue="3" 具體的值參考一下選項

  <string-array name="pref_development_ua_choices" translatable="false">

        <item>Android</item>

        <item>Desktop</item>

        <item>iPhone</item>

        <item>iPad</item>

        <item>Froyo-N1</item>

        <item>Honeycomb-Xoom</item>

    </string-array>

    <!-- Do not tranlsate.  Development option -->

    <string-array name="pref_development_ua_values" translatable="false">

        <item>0</item>

        <item>1</item>

        <item>2</item>

        <item>3</item>

        <item>4</item>

        <item>5</item>





7. workspace 預置 文件夾

范例

folder 放到最前面。launcher:container 的值是folder的數據庫中的id。一般從1開始。

<folder



            launcher:screen="2"

            launcher:x="1"

            launcher:y="1"

            launcher:title ="@string/application_name" >

 

       <favorite

            launcher:className="com.android.settings"

            launcher:packageName="com.android.settings.Settings"

            launcher:container="2"

            launcher:x="0"

            launcher:y="0" />

 

       <favorite

            launcher:className="com.fb.FileBrower"

            launcher:packageName="com.fb.FileBrower.FileBrower"

            launcher:container="2"

            launcher:x="0"

            launcher:y="0" />

    </folder>





widget 范例

<appwidget

        launcher:packageName="com.android.calendar"

        launcher:className="com.android.calendar.widget.CalendarAppWidgetProvider"

        launcher:screen="1"

        launcher:x="0"

        launcher:y="0"

        launcher:spanX="2"

        launcher:spanY="3" />



快捷方式范例

<favorite

        launcher:packageName="com.android.settings"

        launcher:className="com.android.settings.Settings"

        launcher:screen="2"

        launcher:x="1"

        launcher:y="3" />





網頁快捷方式

<shortcut

launcher:title="@string/custom_google"

        launcher:icon="@drawable/favicon_google"

        launcher:uri="http://www.google.com/"

        launcher:screen="3"

        launcher:x="4"

        launcher:y="1"/>

8. 系統自帶LatinIME 高級設置--按鍵音量設置   修改默認值

          java/res/values/keypress-volumes.xml



<string-array name="keypress_volumes" translatable="false">

         <!-- Build.HARDWARE,volume -->

        <item>amlogic,0.3</item>    //加入這行。 把0.3改成自己的默認值。0.3代表30%

         <item>herring,0.5</item>

         <item>tuna,0.5</item>

         <item>stingray,0.4</item>



9.lockscreen坐標數字時鐘被遮住



請調整紅色的數字:


<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_tab_unlock_land.xml>

  <!-- left side: status and music -->

    <RelativeLayout

        android:layout_height="match_parent"

        android:layout_weight="0.5"



    <!-- right side -->

    <RelativeLayout

        android:layout_height="match_parent"

        android:layout_weight="0.5"



10.在4.1上修改默認字體大小:

  比如改成大:

  <frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<fraction name="def_font_scale">115%</fraction>



11.沒有藍牙的平台,去掉窗口小部件-設置快捷方式-拉到桌面顯示的“藍牙”選項

<\packages\apps\Settings\src\com\android\settings\OutputSettingsBroadcastReceiver.java>

public void onReceive(Context context, Intent intent)

{

// boot completed

if(intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED))

{



                     if(!context.getPackageManager().hasSystemFeature(context.getPackageManager().FEATURE_BLUETOOTH)){

                            ComponentName componentname = new ComponentName("com.android.settings", "com.android.settings.Settings$BluetoothSettingsActivity");

                            context.getPackageManager().setComponentEnabledSetting(componentname, 2, 1);

                     }

}



11. 修改 浏覽器的默認標簽

分別在一下資源文件中添加自定義的標簽

packages\apps\Browser\res\values\strings.xml

<string-array name="bookmarks" translatable="false">

        <item>Google</item>

        <item>http://www.google.com/</item>

        <item>Picasa</item>

        <item>http://picasaweb.google.com/</item>

    </array>
對應的圖片在 packages\apps\Browser\res\raw





12. 鎖屏界面, 解鎖組件增加圖標

已增加 VideoPlayer 為例,

在frameworks/base/core/res/res/drawable-hdpi  下面

添加一個對應的png圖標

下面紅色為增加的部分。

frameworks/core/res/res/values-sw600dp-land/arrays.xml

         <item>@drawable/ic_lockscreen_unlock</item>

         <item>@drawable/ic_action_assist_generic</item>

         <item>@drawable/ic_lockscreen_camera</item>

  <java-symbol type="drawable" name="ic_lockscreen_videoplayer" />



   <java-symbol type="layout" name="action_bar_home" />

   <java-symbol type="layout" name="action_bar_title_item" />

   <java-symbol type="layout" name="action_menu_item_layout" />



frameworks/base/policy/src/com/android/internal/policy/impl/LockScreen.java



                 case com.android.internal.R.drawable.ic_lockscreen_camera:

                     launchActivity(new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA));

                     mCallback.pokeWakelock();

                    break;                   

                case com.android.internal.R.drawable.ic_lockscreen_videoplayer:

                     launchActivity(new Intent().setClassName("com.farcore.videoplayer", "com.farcore.videoplayer.FileList"));

                     mCallback.pokeWakelock();

                     break;

注意: 在 frameworks/base/core/res/ 中執行mm 。然後在frameworks/base/policy 中執行mm。看看能否編譯過。不行的話,在 在根目錄下 執行make update-api



13. 休眠策略

修改默認的休眠策略,請參考

frameworks\base\packages\SettingsProvider\res\values\defaults.xml

<integer name="def_wifi_sleep_policy">0</integer>

<!--  0 == Never, 1 == Only when plugged in,2 == Always. -->  

 

14. Launcher 半透明
4.0, 4.1  下載附件中的patch集合--- translucent.zip
如果是 4.2.2系統 , 還需修改

Launcher/src/com/android/launcher2/Launcher.java



         mLauncherView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

         mWorkspaceBackgroundDrawable = getResources().getDrawable(R.drawable.workspace_bg);

         mBlackBackgroundDrawable = new ColorDrawable(Color.BLACK); // 修改為 mBlackBackgroundDrawable = new ColorDrawable(0x7f000000);   

  packages\amlogic\Launcher2\src\com\android\launcher2\Launcher.java



         mStateAnimation.addListener(new AnimatorListenerAdapter() {

                boolean animationCancelled = false;

                @Override

                public void onAnimationStart(Animator animation) {

                    dispatchOnLauncherTransitionEnd(fromView, animated, false); //add

                    dispatchOnLauncherTransitionEnd(toView, animated, false);   //add

                    updateWallpaperVisibility(false);  //true 改成false

                    // Prepare the position

                    toView.setTranslationX(0.0f);

                    toView.setTranslationY(0.0f);

                    toView.setVisibility(View.VISIBLE);

                    toView.bringToFront();

                }




15. APK 預裝時無法找到lib庫的問題



    (1) 如果log報錯是找不到lib庫首先可以修改lib的路徑



jb4.1\frameworks\base\core\java\android\app\NativeActivity.java

public static final String SYSTEM_LIB_PATH = "/system/lib";



       if (libraryFile.exists()) {

            path = libraryFile.getPath();

        }else{

            File systemLibraryFile = new File(SYSTEM_LIB_PATH,System.mapLibraryName(libname));  

            if (systemLibraryFile.exists()) {

                path = systemLibraryFile.getPath();

            }

        }   



(2)apk本身會檢測檢測/data/data/lib路徑是否存在資源文件時方法1不適用,用第二種方法: 



           在項目上的mk文件 /device/amlogic/g18refg/8ref.mk 中,加上 preinstallation



PRODUCT_PACKAGES += \

lights.amlogic \

FileBrowser \

AppInstaller \

VideoPlayer \

HdmiSwitch \

Update \

fw_env \

preinstallation



將網頁底部的附件 Preinstallation.zip拷貝到packages\amlogic下面解壓   將需要預裝安裝的apk拷貝到preinstallation目錄下面,編輯裡面的preinstall.sh文件內容如下:



#!/system/xbin/busybox sh



echo "do preinstall applications"



# com.mxtech.videoplayer.ad apk包名



if [ ! -e /data/data/com.mxtech.videoplayer.ad/ ]; then

  pm install /system/preinstall/com.mxtech.videoplayer.ad.50.apk

fi



if [ ! -e /data/data/org.xbmc.xbmc/ ]; then

  pm install /system/preinstall/xbmc-20130414-e2c3799-Frodo-armeabi-v7a.apk

fi

。。。。。。



然後在device\amlogic\common\init\tablet\init.amlogic.rc 中,啟動預安裝腳本的服務.



MX:

service preinstall /system/bin/preinstall.sh

         class main

         user root

         group root

         oneshot

         console

         disabled    





M3:

service preinstall /system/bin/preinstall.sh

user root

        group root

        disabled

        oneshot



在init.amlogic.rc最後一行加上



start preinstall





16. 去掉 hotspot

把紅色的部分刪掉

device\amlogic\gXXXX\overlay\frameworks\base\core\res\res\values\config.xml

    <string-array translatable="false" name="config_tether_wifi_regexs">

        <item>"wlap0"</item>

        <item>"wl0.1"</item>

        <item>"wlan0"</item>

    </string-array>

    <integer-array translatable="false" name="config_tether_upstream_types">

        <item>0</item>

        <item>9</item>

    </integer-array>



17.桌面上添加快捷方式,點擊播放視頻:

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

<shortcut

launcher:title="@string/application_name"

launcher:icon="@drawable/ic_launcher_application" launcher:uri="file:///mnt/sdcard/external_sdcard/1...playermenu;end"

launcher:screen="2" launcher:x="1" launcher:y="1" />



添加網頁的快捷方式:

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

    <shortcut

        launcher:title="@string/application_name"
        launcher:icon="@drawable/ic_no_applications"
        launcher:uri="http://www.aaa.com"
        launcher:screen="0"
        launcher:x="0"
        launcher:y="3" />



18.去掉camera的全景icon:

4.1:

<\packages\apps\Camera\res\layout-sw600dp-land\mode_picker.xml>

        <com.android.camera.ui.RotateImageView android:id="@+id/mode_panorama"

                android:contentDescription="@string/accessibility_switch_to_panorama"

                android:layout_width="match_parent"

                android:layout_height="wrap_content"

                android:layout_weight="1"

android:visibility="gone"

                android:scaleType="center"

                android:background="@drawable/bg_pressed"

                android:src="@drawable/ic_switch_pan_holo_light" />



4.2:

<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>

加上紅色加亮的地方:

    public void init() {

        for (int i = 0; i < mDrawables.length; i++) {

            if ((i == LIGHTCYCLE_MODULE_INDEX && !LightCycleHelper.hasLightCycleCapture(this))||i == PANORAMA_MODULE_INDEX) {

                continue; // not enabled, so don't add to UI

            }

            drawids[ix++] = DRAW_IDS[i];

        }



<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>

    public void init() {

        int[] drawids = new int[LightCycleHelper.hasLightCycleCapture(this)

                                ? DRAW_IDS.length -1 : DRAW_IDS.length - 2];



19.鎖屏左邊clock太大顯示不全:

<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_status_land.xml>

        <TextView android:id="@+id/timeDisplayBackground"

android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"



<TextView android:id="@+id/timeDisplayForeground"

android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"



//dimens.xml裡的keyguard_pattern_unlock_clock_font_size調小



可以把clock調成居中顯示,不要靠右,造成右邊顯示不全

<LinearLayout

        xmlns:android="http://schemas.android.com/apk/res/android"

        android:orientation="vertical"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:gravity="right">

//改成center



20. 去掉settings的battery裡面的mobile network signal顯示

加上紅色語句:

<\packages\apps\Settings\src\com\android\settings\fuelgauge\BatteryHistoryChart.java>

        if (!com.android.settings.Utils.isWifiOnly(getContext())) {

            mHavePhoneSignal = true;

        }

        mHavePhoneSignal = false;     



21. 去掉待機的CRT動畫

把自己項目overlay中的

frameworks/base/core/res/res/values/config.xml

<bool name="config_animateScreenLights">false</bool> 刪掉 就可以了




22. 添加格式化內部sdcard

jb4.1\packages\amlogic\Settings\src\com\android\settings\deviceinfo\StorageVolumePreferenceCategory.java



       public StorageVolumePreferenceCategory(Context context, Resources resources, StorageVolume storageVolume, StorageManager storageManager, boolean isPrimary) {

// Cannot format emulated storage

        mAllowFormat = mStorageVolume != null && !mStorageVolume.isEmulated()&&mStorageVolume.isRemovable();

        // For now we are disabling reformatting secondary external storage

        // until some interoperability problems with MTP are fixed

        //if (!isPrimary) mAllowFormat = false;

     

+        if(mStorageVolume != null && mStorageVolume.getPath().equals("/storage/sdcard0")){

+            mAllowFormat = true;

+        }



23. 4.2 LockScreen 任何方向都可以解鎖, 修改成只有向右才能解鎖

4.2 Lockscreen 對應的java 文件不再是 Lockscreen, 而是KeyguardSelectorView.java



frameworks/base/core/res/res/values/arrays.xml b/core/res/res/values/arrays.xml



     <array name="lockscreen_targets_unlock_only">

         <item>@*android:drawable/ic_lockscreen_unlock</item>

+       <item>@null</item>

+       <item>@null</item>

+       <item>@null</item>

     </array>



     <array name="lockscreen_target_descriptions_unlock_only">

         <item>@*android:string/description_target_unlock</item>

+       <item>@null</item>

+       <item>@null</item>

+       <item>@null</item>

     </array>



24.android 4.2改launcher裡面的icon橫排的數目:

<\packages\apps\Launcher2\res\values-sw720dp\config.xml>

<integer name="cell_count_x">7</integer>



如果改成7,hotseat裡面第8個icon不見了,可以往第8個槽裡面放進去,但是重啟後,icon又不見了,可以這樣修改:

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>
                final ItemInfo occupied[][][] =
                        new ItemInfo[Launcher.SCREEN_COUNT + 1][mCellCountX + 2][mCellCountY + 1]; //原來這裡是+1









25. 4.2 LockScreen 解鎖界面四個方向添加一個setting入口

frameworks\base\core\res\res\values/arrays.xml

    <array name="lockscreen_targets_with_camera">

        <item>@drawable/ic_lockscreen_unlock</item>

        <item>@drawable/ic_action_assist_generic</item>

        <item>@drawable/ic_lockscreen_camera</item>

        <item>@drawable/ic_lockscreen_settings</item>

    </array>



在 frameworks\base\core\res\res\drawable 增加 ic_lockscreen_settings.xml 文件 並添加 ic_lockscreen_settings_normal.phg ic_lockscreen_settings_activated.png 資源文件



<selector xmlns:android="http://schemas.android.com/apk/res/android">



<item

        android:state_enabled="true"

        android:state_active="false"

        android:state_focused="false"

        android:drawable="@drawable/ic_lockscreen_settings_normal" />



    <item

        android:state_enabled="true"

        android:state_active="true"

        android:state_focused="false"

        android:drawable="@drawable/ic_lockscreen_settings_activated" />



    <item

        android:state_enabled="true"

        android:state_active="false"

        android:state_focused="true"

        android:drawable="@drawable/ic_lockscreen_settings_activated" />

</selector>




frameworks\base\policy\src\com\android\internal\policy\impl\LockScreen.java

     public void onTrigger(View v, int target) {

            final int resId = mGlowPadView.getResourceIdForTarget(target);

            switch (resId) {

              

                 case com.android.internal.R.drawable.ic_lockscreen_settings: //啟動setting 應用

                    launchActivity(new Intent().setComponent(new ComponentName("com.android.settings","com.android.settings.Settings")));  

                    mCallback.pokeWakelock();

                    break;







26. 4.2 上隱藏 Wifi Display

  去掉項目overlay/frameworks/base/core/res/res/config.xml 中的config_enableWifiDisplay



27. 默認音量修改

frameworks/base/media/java/android/media/AudioService.java

private final int[] MAX_STREAM_VOLUME = new int[] {

        5,  // STREAM_VOICE_CALL

        7,  // STREAM_SYSTEM

        7,  // STREAM_RING

        15, // STREAM_MUSIC

        7,  // STREAM_ALARM

        7,  // STREAM_NOTIFICATION

        7,  // STREAM_SYSTEM_ENFORCED

        15, // STREAM_DTMF

        15  // STREAM_TTS

    };



frameworks/base/media/java/android/media/AudioManager.java



/**  @hide  Default volume index values for audio streams */

    public static final int[] DEFAULT_STREAM_VOLUME = new int[] {

        4,  // STREAM_VOICE_CALL

        7,  // STREAM_SYSTEM

        5,  // STREAM_RING

        11, // STREAM_MUSIC

        6,  // STREAM_ALARM

        5,  // STREAM_NOTIFICATION

        7,  // STREAM_BLUETOOTH_SCO

        7,  // STREAM_SYSTEM_ENFORCED

        11, // STREAM_DTMF

        11  // STREAM_TTS

    };



28.widget中隱藏google play:

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>

updatePackages裡面添加:

if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){

    mWidgets.add(widget);

}



29.去掉設置-->顯示-->亮度裡的“自動調整亮度”選項

<\packages\apps\Settings\res\layout\preference_dialog_brightness.xml>

        <CheckBox android:id="@+id/automatic_mode"

加上

    android:visibility="invisible"



30.設置-位置信息訪問權限默認關閉

<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<string name="def_location_providers_allowed" translatable="false"></string>

這裡不要填寫gps或者network,清空



31.設置-安全-驗證應用默認不勾允

<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<bool name="def_package_verifier_enable">false</bool>



32.設置-聲音-觸摸提示音與鎖屏提示音默認不勾允狀態

<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<integer name="def_lockscreen_sounds_enabled">0</integer>

<bool name="def_sound_effects_enabled">false</bool>



33.設置-以太網菜單請移動“更多”菜單下

請用附件ethernet.patch,開關是ro.ethernet.more,設置為true,ethernet移到more裡面

在settings的git下打這個patch



34.窗口小部件“指針時鐘”顯示不全

把clock的widget向上調,下面的值改小:

<\packages\amlogic\Launcher2\res\values\dimens.xml>

<dimen name="app_widget_preview_padding_top">10dp</dimen>



35.去掉settings的more裡面的網絡共享與便攜式熱點

ro.tether.denied=true



36.平台主界面底部工具欄上的圖標全部居中顯示,從左至右的圖標依次為:vol-、back、home、窗口切換、vol+

1.在prop裡面將ro.statusbar.volume設置為true

2.<\frameworks\base\packages\SystemUI\res\layout-sw600dp\navigation_bar.xml>



<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/sub"

……

/>

這段放到

<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/back"

……

/>

這段之前



<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/add"

……

/>

這段放到

<com.android.systemui.statusbar.policy.KeyButtonView

android:id="@+id/recent_apps"

……

/>

這段之後



注意這個文件有兩處需要調換上面的



37.主界面模擬時鐘改成數字時鐘

default_workspace.xml裡面加上:

<appwidget

    launcher:packageName="com.android.deskclock"

    launcher:className="com.android.alarmclock.DigitalAppWidgetProvider"



38、settings中的developer options的開關打開,debug關掉:

<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>

    private void loadSecureSettings(SQLiteDatabase db) {

       loadSetting(stmt, Settings.Secure.ADB_ENABLED, 0);
       loadSetting(stmt, Settings.Secure.DEVELOPMENT_SETTINGS_ENABLED, 1);



39、改桌面icon行、列數:

<\packages\apps\Launcher2\res\layout-sw***dp\workspace.xml>

    launcher:cellCountX="10"

    launcher:cellCountY="6"



40、more裡面morebile data項默認不選:

1.<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>

    private void loadSecureSettings(SQLiteDatabase db) {

        SQLiteStatement stmt = null;

        try {

            stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)"

                    + " VALUES(?,?);");

添加:

            loadIntegerSetting(stmt, Settings.Secure.MOBILE_DATA,

                    R.integer.def_mobile_data);



2.<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<integer name="def_mobile_data">0</integer>



41.secure的unknown的設置默認打開:

<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

   <bool name="def_install_non_market_apps">true</bool>



42、修改app list的背景:

<\packages\apps\Launcher2\res\layout\apps_customize_pane.xml>

<com.android.launcher2.AppsCustomizeTabHost

    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:launcher="http://schemas.android.com/apk/res/c...droid.launcher"

    android:background="@drawable/wallpaper_03">



43、bluetooth tethering的checkbox去掉:

overlay裡面的

<\frameworks\base\core\res\res\values\config.xml>


     <string-array translatable="false" name="config_tether_bluetooth_regexs">
        <item>"bt-pan"</item>
    </string-array>

去掉<item>"bt-pan"</item>



44. Google play 不是內置, 而是安裝,導致出問題的解決辦法

frameworks/baseservices/java/com/android/server/pm/PackageManagerService.java

@@ -4594,6 +4594,9 @@ public class PackageManagerService extends IPackageManager.Stub {

                             }

                         }

                     }

+                   if (pkg.packageName.equals("com.android.vending")){

+                       allowed = true;

+                   }

                     if (!allowed && (bp.protectionLevel

                             & PermissionInfo.PROTECTION_FLAG_DEVELOPMENT) != 0) {

                         // For development permissions, a development permission




45.以太網設置問題

以太網在settings.db中的條目是"eth_on", 默認值由系統屬性 ro.ethernet.default_on 決定,

ro.ethernet.default_on=false 默認關閉

ro.ethernet.default_on=true默認打開

不定義該屬性默認關閉

46.開機不停震動
手機開機,馬達一直震動,應該是uboot正常啟動後,沒有設置震動關閉
解決:在震動200ms後關閉馬達
u-boot/property/normal_mode.c
void normal_mode(void)
{
//MMU_Init(CONFIG_MMU_TABLE_ADDR);
vibrator_hw_init();


set_vibrator(1);
udelay(200*1000);
set_vibrator(0);
...
}


47.關機震動時間設置
frameworks/base/core/java/com/android/internal/app/ShutdownThread.java中
private static final int SHUTDOWN_VIBRATE_MS = 500;   //默認震動0.5秒,修改這個參數




48.設置系統默認音量
修改文件:frameworks/base/media/java/android/media/AudioManager.java
public static final int[] DEFAULT_STREAM_VOLUME = new int[] {
         4,  // STREAM_VOICE_CALL
         7,  // STREAM_SYSTEM
         5,  // STREAM_RING
         11, // STREAM_MUSIC
         6,  // STREAM_ALARM
         5,  // STREAM_NOTIFICATION
         7,  // STREAM_BLUETOOTH_SCO
         11, // STREAM_FM
         11, // STREAM_DTMF
         11, // STREAM_TTS
         7  // STREAM_SYSTEM_ENFORCED
     };
根據需要進行修改即可。
注意:如果在3rdparty裡面有同名文件最好一起修改。


49.如何調節音量檔位
需要根據自己的情況來調整index to volume的算法。
相關實現的模塊是 AudioPolicy。基類 AudioPolicyManagerBase 文件位於
framework/base/services/audioflinger/AudioPolicyManagerBase.cpp
實現類 AudioPolicyManagerALSA,位於
external/sprd/alsa/alsa_sound/AudioPolicyManagerALSA.cpp
函數 computeVolume:
這個方法平台目前沒有用子類實現,所以走的是基類方法。如果客戶需要修改,建議在子類中重載這
個方法。
再講下基類方法:
1 通過 index 算出一個百分比;
2 通過這個百分比經過一個對數轉換換成音量的百分比;
3 特殊情況的一些轉換;
修改建議是子類的方法應該調用基類的方法並且做微調。
比如對 1,將 index 到百分比的對應關系略微修改。
比如對 3,可以把基類方法處理的結果在根據需要調整。


50.電池相關
若手機界面的電池進度條顯示不夠准確,請根據實際測試值調整kernel\drivers\ power\charge.c 的voltage_capacity_table表格中的值 15%對應的是低電告警電壓,而0%是自動關機電壓。
電池的報警電壓調整:frameworks\base\core\res\res\values\config.xml,
config_lowBatteryWarningLevel:15----->百分比,可以動態調整該數值來調整低電電壓。
過壓保護的邏輯在:
Kernel\drivers\power\sprd_power.c裡
charge_handler()函數中有個battery_data->over_voltage用於電壓保護邏輯。
這個數值的來源是Kernel\arch\arm\mach-sc8810\include\mach\chg_drvapi.h
#define OVP_OVER_VOL 6500


51.修改系統默認時間:
修改\idh.code\kernel\drivers\rtc\ rtc-sprd.c
static int __init sprd_rtc_init(void)
{
......
sec_2011_to_1970 = mktime(2011, 1, 1, 0, 0, 0);
return 0;
}
mktime函數的參數即是修改點。
同時還要同步修改鬧鐘時間,否則鬧鐘會有問題。
packages\apps\DeskClock\src\com\android\deskclock\Alarms.java
private static void alarm_flag_setup(final long alarmTimeInMillis) {
Calendar c = Calendar.getInstance();
c.set(2011, 0, 1, 0, 0, 0);//注意這裡月份是0代表1月
......


52.如何設置版本號
定義 android 版本號的地方在 build/tools/buildinfo.sh 內,可以修改此文件。
ro.build.display.id=$BUILD_DISPLAY_ID 改為 ro.build.display.id= $BUILD_D ISPLAY_ID_CUSTOM, 然 後 在customize/custom_cfg/proj_name/res/boardconfig.mk
下 定 義 宏BUILD_DISPLAY_ID_CUSTOM 就可以為自己的項目定義版本號.
顯示硬件版本在設置->關於手機->硬件版本裡看到:
packages/apps/Settings/res/xml/device_info_settings.xml
<Preference android:key="hardware_number"

android:title="@string/hard_version"
android:summary="1.1.0"/>


53.無接近傳感器,如何在開始通話後關閉屏幕
在 Phone 應用的 phoneApp 這個類中。找到下邊這段代碼:
mProximityWakeLock =
pm.newWakeLock(PowerManager.PROXIMITY_SCREEN_OFF_WAKE_LOCK, LOG_TAG);
然後注釋掉。這個是獲取了接近傳感器的 WakeLock。然後在 updatePokeLock 這個方法中。將
//pokeLockSetting |= LocalPowerManager.POKE_LOCK_MEDIUM_TIMEOUT;
改為
pokeLockSetting |= LocalPowerManager.POKE_LOCK_SHORT_TIMEOUT;
將updateWakeState 方法中
setScreenTimeout(ScreenTimeoutDuration.DEFAULT);
改為
setScreenTimeout(ScreenTimeoutDuration.SHORT);
這個是將默認延時時間設置為SHORT(5秒)。如果需要改為其他時間需要去改 setScreenTimeout
這個方法。


54.ms,mms,contact 容量限制
[適用版本]2.3.5
1.只要在容量允許的情況下,sms,mms 接收條數是沒有限制的,但是每個會話的條數是有限
制的,默認情況下,每個會話的短信限存 200 條,彩信限存 20 條,但是能調整到 5000 條。
MmsConfig.java 代碼中做了如下限制:
private static int mDefaultSMSMessagesPerThread = 200;// default value
private static int mMinMessageCountPerThread = 2; // default value
private static int mMaxMessageCountPerThread = 5000; // default value
private static int mDefaultMMSMessagesPerThread = 20; // default value
2.contact 的記錄總數目前沒有限制。


55.單攝像頭進入時間較長如何解決
在customize/customer_cfg/project.../kernel/camera/camera_cfg.c中main_sensor_infor_tab和sub_sensor_infor_tab裡會放很多sensor的結構體;camera啟動初始化時,底層驅動會匹配相關的菜單,刪除沒有的sensor,能加快啟動


56.客戶定制開/關機鈴聲
開機:替換 3rdparty/anim/poweranim/special/bin/startupsound
關機:替換 3rdparty/anim/poweranim/special/bin/shutdownsound
注:這裡的startupsound/shutdownsound可以是mp3或者ogg格式的,替換時不需要擴展名


57.背光亮度,靜音等默認值修改
修改\frameworks\base\packages\SettingsProvider\res\values\defaults.xml中的默認值即可。


58.浏覽器如何修改內置的“搜索引擎”
修改packages\apps\browser\res\values\donoottranslate-search_engines,xml文件,中
“search_engines”的string-arry中的item項即可。如下事例為內置了 139/百度/google 三個搜索引
擎。
<item>search139</item>
<item>baidu</item>
</string-array>
<item>google</item>
<string-array name="search_engines" translatable="false">
注意:如果支持多種語言,其他文件下的同名文件donoottranslate-search_engines,xml也需要
修改。


59.關機充電動畫修改
關機充電動畫的資源路徑是:
external/sprd/charge/res/images/(展訊平台)
將這個目錄下的 png 圖片文件修改客戶需要的文件就可以了。


60.如何設置默認動態壁紙
找到 /frameworks/base/core/res/res/values/config.xml 文件中
<string name="default_wallpaper_component">@null</string>
為設置默認壁紙的代碼如若想要更換成為動態壁紙[email protected],例如:將默認壁紙更改為“線性光幕效果”的動態壁紙,則更改成如下代碼:
<string name="default_wallpaper_component">com.android.wallpaper/com.android.wallpaper.nexus.NexusWallpaper</string>
com.android.wallpaper 在 AndroidManifest 文件中的 packagename
com.android.wallpaper.nexus.NexusWallpaper 在 AndroidManifest 文件中的 service name
需要注意的是:靜態的圖片壁紙和 live wallpaper 是兩個系統,加載的時候是完全兩套機制,靜態圖片
通過 launcher 裡面的一個 xml 文件配置來管理系統默認靜態壁紙,live wallpaper 則是通過 intent 機制向系統搜尋所有匹配 Activity,所以,這裡的默認值為 null,而不是那個系統默認靜態壁紙的地址,系統是讀 config.xml 文件的設置,若為 null 才繼續查找靜態壁紙配置內容. 沒有效果的話,恢復下出廠設置即可。


61.如何設置系統默認壁紙
如果只需要修改動態壁紙,替換 frameworks/base/core/res/res/drawable/default_wallpaper.jpg即可,或者在源碼中修改對應 default_wallpaper地址。


62.關機菜單中如何添加重啟選項
/frameworks/base/policy/src/com/android/internal/policy/impl/GlobalActions.java" 文件添加如下修改部分即可:
mItems = Lists.newArrayList(
// silent mode
mSilentModeToggle,
// next: airplane mode
mAirplaneModeOn,
new SinglePressAction(
                         com.android.internal.R.drawable.ic_lock_power_off,
                         R.string.global_action_power_off) {
                     public void onPress() {
           // shutdown by making sure radio and power are handled accordingly.
                         ShutdownThread.shutdown(mContext, true);
                     }


                    public boolean showDuringKeyguard() {
                         return true;
                     }


                    public boolean showBeforeProvisioning() {
                         return true;
                     }
                 },
// add for reboot
new SinglePressAction(
          com.android.internal.R.drawable.ic_lock_power_off, //替換成相應的圖
          R.string.global_action_power_off) { //替換成相應的提示文字
          public void onPress() {
            ShutdownThread.reboot(mContext, null, true);
          }


         public boolean showDuringKeyguard() {
            return true;
          }


         public boolean showBeforeProvisioning() {
            return true;
          }
       });
//end add


63.如何修改系統默認輸入法
下面將以“谷歌拼音輸入法”為例,進行解釋和說明。
第一步 修改/frameworks/base/packages/SettingsProvider/res/values/defaults.xml 添加如下代碼:
<string name="config_default_input_method"
translatable="false">com.android.inputmethod.pinyin/.PinyinIME</string>


com.android.inputmethod.pinyin 在 AndroidManifest 文件中的 packagename
.PinyinIME 在 AndroidManifest 文件中的service name
第二步:修改
/frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java
在 private void loadSecureSettings(SQLiteDatabase db) 方法中,添加如下代碼:
loadStringSetting( stmt, Settings.Secure.DEFAULT_INPUT_METHOD,
R.string.config_default_input_method );


64.如何在桌面預置應用程序圖標
桌面預制的圖標:是在 launcher2 的 default_workspace.xml中配置的,文件路徑:
Launcher2\res\xml\default_workspace.xml


65.添加搜索引擎
以添加139搜索引擎為例
a) 在packages/apps/Browser/res/values/all_search_engines.xml
<string-array name="search139" translatable="false">
<item>139</item>
<item></item>
<item>http://s.139.com/favicon.ico</item>
<item>http://s.139.com/search.do?q={searchTerms}&amp;category=downloadable|web|browseable&amp;tid=2123,2124,2125,2126&amp;fr=portalcustom2</item>
<item>UTF-8</item>
<item></item>
</string-array>
這6個<item>從上到下依次表示顯示標簽,關鍵字,搜索圖標,搜索引擎地址,編碼方式,搜索提示地址。
b) 在packages/apps/Browser/res/values/donottranslate-search_engines.xml
<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
<string-array name="search_engines" translatable="false">
<item>search139</item>
<item>baidu</item>
<item>google</item>
<item>yahoo</item>
<item>bing</item>
</string-array>
</resources>
在這邊將139搜索引擎添加進來。
這邊添加的搜索引擎是將1中的添加的搜索引擎變成設置中選擇搜索引擎的選項。


66.修改 idle 界面搜索引擎的鏈接地址
packages/apps/quicksearchbox/res/values/strings.xml 下修改:
www.google.com為www.google.com.hk


67.linux下ADB安裝後增加設備權限:
/etc/udev/rules.d/51-Android.rules
SUBSYSTEM=="usb", SYSFS{"huawei"}=="12d1", MODE="0666"   //華為設備號
SUBSYSTEM=="usb", SYSFS{"Samsung"}=="04e8", MODE="0666"  //三星設備號




68.隱藏editText的軟鍵盤

在相應的配置文件中加入紅色部分如下:

     <EditText
        android:layout_width="wrap_content"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_height="wrap_content"
        android:id="@+id/editText"
        android:layout_below="@+id/textView"
        android:layout_alignParentStart="true" />
