編輯：關於Android編程
首先弄懂怎麼設置adb wifi無線調試的功能，如下所示。
1. 手機端開啟adb tcp連接端口
:/$setprop service.adb.tcp.port 5555 :/$stop adbd :/$start adbd
其中setprop是用來設置系統屬性的，這裡不需要root權限，su即可。可通過adb shell設置，亦可通過手機上安裝的Android terminal設置。
2. 電腦端的設置和使用
連接adb，其中phone_ipaddress和portnumber是指手機的ip和前面設置的監聽端口號（如5555）
adb connect phone_ipaddress:portnumber
直接adb shell或adb -s 設備shell連接設備
如若要斷開則如下：
adb disconnect phone_ipaddress:port
但是每次這樣的去設置很繁瑣，所以直接在設置中做一個開關就把手機端的設置做好，如下所示：
一、打開開關，並連接Wifi
二、打開開關，沒有連接Wifi
三、未打開開關
這樣就可以直接進行adb wifi調試了，手機端就不用每次都先用USB調試去設置修改的屬性，才能激活adb wifi調試。
======================================================================================================
下面來具體說說實現的思路：
第一步：在【設置】-->【開發者選項】中做一個類似於【USB調試】的開關【Wifi調試】
第二步：【Wifi調試】開關打開就激活監聽5555端口，用來進行adb wifi調試，【Wifi調試】開關關閉就不監聽5555端口，這樣就不能進行adb wifi調試
第三步：在第二步中打開關閉【Wifi調試】開關的時候，調用相應的接口進行設置
第四步：將第三步中要調用的接口寫好
1、先在布局中加入該開關
首先找到布局文件，packages/apps/Settings/res/xml/development_prefs.xml，找到【USB調試】開關的相應代碼，然後再裡面加一個【Wifi調試】開關，代碼如下：
<SwitchPreference android:key="enable_adb" android:title="@string/enable_adb" android:summary="@string/enable_adb_summary"/><!-- added by ouyang start --><SwitchPreference android:key="enable_wifi_adb" android:title="@string/enable_wifi_adb" android:summary="@string/enable_wifi_adb_summary"/> <!-- added by ouyang end -->上面代碼中，第一個代碼是【USB調試】開關的代碼，第二個是我加的【Wifi調試】開關的代碼，然後為什麼的字符串做相應的國際化操作，代碼如下：
packages/apps/Settings/res/values-zh-rCN/strings.xml 中加入：
<!-- added by ouyang start 2015-12-17 --> <string name="enable_wifi_adb">Wifi調試</string> <string name="enable_wifi_adb_openwifi">Wifi沒連接，請連接wifi</string> <string name="enable_wifi_adb_summary">連接Wifi後啟用調試模式</string> <string name="enable_wifi_adb_connected_summary">Wifi調試已打開,在電腦端你可以輸入以下命令進行調試:/n adb connect <xliff:g id="ip_address">%1$s</xliff:g>:5555</string> <!-- added by ouyang end 2015-12-17 -->
<!-- added by ouyang start 2015-12-17 --> <string name="enable_wifi_adb">Wifi debugging</string> <string name="enable_wifi_adb_openwifi">Wifi is not connected,please turn wifi on and connect it</string> <string name="enable_wifi_adb_summary">Debug mode when Wifi is connected</string> <string name="enable_wifi_adb_connected_summary">adb wifi is on,from your computer run:/n adb connect <xliff:g id="ip_address">%1$s</xliff:g>:5555</string> <!-- added by ouyang end 2015-12-17 -->
2、在packages/apps/Settings/src/com/android/settings/DevelopmentSettings.java文件中，對剛才加入的【Wifi調試】開關進行相關的邏輯處理。
首先先定義開關的幾個變量，如下：
//add by ouyang 2015-12-17 start
private static final String ENABLE_WIFI_ADB = "enable_wifi_adb";
private static final String ADB_WIFI_ENABLED_KEY = "ADB_WIFI_ENABLED";
private static SwitchPreference mEnableWifiAdb;
//add by ouyang 2015-12-17 end
然後再onCreate()方法中初始化【Wifi調試】開關，如下：
mEnableAdb = findAndInitSwitchPref(ENABLE_ADB); //add by ouyang 2015-12-17 mEnableWifiAdb = findAndInitSwitchPref(ENABLE_WIFI_ADB);然後在onPreferenceTreeClick(PreferenceScreen preferenceScreen, Preference preference)方法中對【Wifi調試】開關的打開和關閉操作做邏輯處理。
if (preference == mEnableAdb) {
if (mEnableAdb.isChecked()) {
mDialogClicked = false;
if (mAdbDialog != null) dismissDialogs();
mAdbDialog = new AlertDialog.Builder(getActivity()).setMessage(
getActivity().getResources().getString(R.string.adb_warning_message))
.setTitle(R.string.adb_warning_title)
.setPositiveButton(android.R.string.yes, this)
.setNegativeButton(android.R.string.no, this)
.show();
mAdbDialog.setOnDismissListener(this);
} else {
Settings.Global.putInt(getActivity().getContentResolver(),
Settings.Global.ADB_ENABLED, 0);
mVerifyAppsOverUsb.setEnabled(false);
mVerifyAppsOverUsb.setChecked(false);
/// M: ALPS01256802, The "Developer options" status is opened.
onPreferenceTreeClick(null, mVerifyAppsOverUsb);
updateBugreportOptions();
}
}
//add by ouyang 2015-12-17 start
else if (preference == mEnableWifiAdb) {
if (mEnableWifiAdb.isChecked()) {
Settings.Global.putInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 1);
android.os.SystemProperties.set("sys.connect.adb.wifi","1");
WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
String ipAddressString = (ipAddress & 0xFF ) + "." +((ipAddress >> 8 ) & 0xFF) + "." +
((ipAddress >> 16 ) & 0xFF) + "." +( ipAddress >> 24 & 0xFF) ;
Log.i(TAG, "ipAddress="+ipAddress);
Log.i(TAG, "ipAddressString="+ipAddressString);
if ("0.0.0.0".equals(ipAddressString)) {
mEnableWifiAdb.setSummary(getResources().getString(R.string.enable_wifi_adb_openwifi));
}else{
mEnableWifiAdb.setSummary(getResources().
getString(R.string.enable_wifi_adb_connected_summary,ipAddressString));
}
} else {
Settings.Global.putInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 0);
android.os.SystemProperties.set("sys.connect.adb.wifi","0");
mEnableWifiAdb.setSummary(getResources().getString(R.string.enable_wifi_adb_summary));
}
}
//add by ouyang 2015-12-17 end
當【Wifi調試】開關打開的時候，保存一個原來表示該【Wifi調試】開關打開關閉的狀態的值為1，然後調用接口android.os.SystemProperties.set("sys.connect.adb.wifi","1");如果wifi這個時候打開就顯示相應的adb wifi命令，如ip地址為192.168.107.201的時候就顯示，"Wifi調試已打開,在電腦端你可以輸入以下命令進行調試:adb connect 192.168.107.201:5555"；如果wifi為打開，就提示“Wifi沒連接，請連接wifi”
當【Wifi調試】開關關閉的時候，保存一個原來表示該【Wifi調試】開關打開關閉的狀態的值為0，然後調用接口android.os.SystemProperties.set("sys.connect.adb.wifi","0");
ADB_WIFI_ENABLED_KEY這個狀態值，在進入該Activity的時候，如果上次打開了【Wifi調試】開關，那麼下次進來的時候就要顯示【Wifi調試】開關是打開狀態，否則是關閉狀態。下面說說ADB_WIFI_ENABLED_KEY這個狀態值的相關代碼，如下：
在onResume()方法中，加入下面代碼：
//add by ouyang 2015-12-17 start
IntentFilter filter = new IntentFilter();
filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
getActivity().registerReceiver(wifiBroadcastReceiver, filter);
boolean isAdbWifiChecked = Settings.Global.getInt(getActivity().getContentResolver(),ADB_WIFI_ENABLED_KEY, 0) != 0;
mEnableWifiAdb.setChecked(isAdbWifiChecked);
Log.i(TAG, "isAdbWifiChecked:" + isAdbWifiChecked);
//add by ouyang 2015-12-17 end
代碼的意思是，進入該Activity就動態的注冊一個廣播，用來監聽Wifi的狀態改變的，然後來動態的顯示Android手機獲取的IP地址。然後根據ADB_WIFI_ENABLED_KEY這個狀態值來顯示【Wifi調試】開關的打開關閉狀態。
在updateAllOptions()方法中，也要去做下處理，代碼如下：
/// M: CR ALPS00244115. Lock and unlock screen, the "USB debugging" is unchecked.
boolean isChecked = (mAdbDialog != null && mAdbDialog.isShowing()) ? true :
(Settings.Global.getInt(cr, Settings.Global.ADB_ENABLED, 0) != 0);
updateSwitchPreference(mEnableAdb, isChecked);
//add by ouyang 2015-12-17 start
boolean isAdbWifiChecked = Settings.Global.getInt(cr,ADB_WIFI_ENABLED_KEY, 0) != 0;
updateSwitchPreference(mEnableWifiAdb, isAdbWifiChecked);
//add by ouyang 2015-12-17 end
/// M: update usb preference again
mExt.customUSBPreference(mEnableAdb);
//add by ouyang 2015-12-17
mExt.customUSBPreference(mEnableWifiAdb);
BroadcastReceiver wifiBroadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String TAG = "wifiBroadcastReceiver";
boolean isAdbWifiChecked = mEnableWifiAdb.isChecked();
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo net = connectivityManager.getActiveNetworkInfo();
if (net == null) {
Log.i(TAG, "No net type");
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(getResources()
.getString(R.string.enable_wifi_adb_openwifi));
}
} else {
Log.i(TAG, "Net Type:" + net.getTypeName());
}
State wifi = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();
if (wifi == State.CONNECTED || wifi == State.CONNECTING) {
Log.i(TAG, "wifi connected");
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
String ipAddressString = (ipAddress & 0xFF) + "." + ((ipAddress >> 8) & 0xFF) + "."
+ ((ipAddress >> 16) & 0xFF) + "." + (ipAddress >> 24 & 0xFF);
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(
getResources().getString(
R.string.enable_wifi_adb_connected_summary, ipAddressString));
}
Log.i(TAG, getResources().getString(
R.string.enable_wifi_adb_connected_summary, ipAddressString));
} else if (wifi == State.DISCONNECTED || wifi == State.DISCONNECTING) {
Log.i(TAG, "wifi disconnected");
if (isAdbWifiChecked) {
mEnableWifiAdb.setSummary(
getResources().getString(R.string.enable_wifi_adb_openwifi));
}
Log.i(TAG, getResources().getString(
R.string.enable_wifi_adb_connected_summary));
}
}
};
======================================================================================================
好吧，在packages/apps/Settings/，即Settings APP層面的代碼寫完了，下面來說說調用的兩個接口怎麼實現。
android.os.SystemProperties.set("sys.connect.adb.wifi", "1");
android.os.SystemProperties.set("sys.connect.adb.wifi", "0");
首先找到frameworks/base/core/java/android/os/SystemProperties.java文件，找到set(String key, String val)方法，代碼如下，發現調用了native_set(key, val)方法。
/**
* Set the value for the given key.
* @throws IllegalArgumentException if the key exceeds 32 characters
* @throws IllegalArgumentException if the value exceeds 92 characters
*/
public static void set(String key, String val) {
if (key.length() > PROP_NAME_MAX) {
throw new IllegalArgumentException("key.length > " + PROP_NAME_MAX);
}
if (val != null && val.length() > PROP_VALUE_MAX) {
throw new IllegalArgumentException("val.length > " +
PROP_VALUE_MAX);
}
native_set(key, val);
}
native_set(key, val)方法定義如下：
private static native void native_set(String key, String def);該接口類在初始化運行環境中注冊對應的cpp接口android_os_SystemProperties.cpp，實際操作通過JNI調用的是cpp文件對應的接口：
frameworks/base/core/jni/AndroidRuntime.cpp
namespace android {
extern int register_android_os_SystemProperties(JNIEnv *env);
}
static void SystemProperties_set(JNIEnv *env, jobject clazz,
jstring keyJ, jstring valJ)
{
int err;
const char* key;
const char* val;
if (keyJ == NULL) {
jniThrowNullPointerException(env, "key must not be null.");
return ;
}
key = env->GetStringUTFChars(keyJ, NULL);
if (valJ == NULL) {
val = ""; /* NULL pointer not allowed here */
} else {
val = env->GetStringUTFChars(valJ, NULL);
}
err = property_set(key, val);
env->ReleaseStringUTFChars(keyJ, key);
if (valJ != NULL) {
env->ReleaseStringUTFChars(valJ, val);
}
if (err < 0) {
ALOGE("setproperty key=%s value=%s err=%d\n", key, val, err);
jniThrowException(env, "java/lang/RuntimeException",
"failed to set system property");
}
}
http://blog.csdn.net/ameyume/article/details/8056492
http://www.blogjava.net/anymobile/articles/301989.html
下面直接寫下面兩個接口的實現
android.os.SystemProperties.set("sys.connect.adb.wifi", "1");
android.os.SystemProperties.set("sys.connect.adb.wifi", "0");
在device/lentek/lentk6735_66t_l1/E580/init.rc文件中加入下面的代碼，其中E580是項目的名稱。
#added by ouyang start connect adb with wifi on property:sys.connect.adb.wifi=1 setprop service.adb.tcp.port 5555 stop adbd start adbd on property:sys.connect.adb.wifi=0 setprop service.adb.tcp.port "" stop adbd start adbd #added by ouyang end connect adb with wifi上面代碼就是當調用
android.os.SystemProperties.set("sys.connect.adb.wifi", "1");和sys.connect.adb.wifiandroid.os.SystemProperties.set("sys.connect.adb.wifi", "0");接口的時候的具體實現，
即"sys.connect.adb.wifi"屬性設置為1的時候，監聽5555端口，
"sys.connect.adb.wifi"屬性設置為0的時候，不監聽任何端口
====================================================================================
好了，下面來再一次測一測該功能怎麼樣，重新打開wifi,重新打開【Wifi調試】開關，顯示如下：
可以看出來，此時Android手機的IP地址是192.168.107.168，因此下面在PC端測試看是否可以用adb wifi無線調試，使用命令adb connect 192.168.107.168連接,adb disconnect 192.168.107.168斷開連接，如下圖所示：
