Android實現開機自啟動Service

一，首先做一個監聽器：

public class StartBroadcastReceiver extends BroadcastReceiver{
private static final String ACTION = "android.intent.action.BOOT_COMPLETED";

public void onReceive(Context context, Intent intent) {
                if (intent.getAction().equals(ACTION)){
                      Intent i= new Intent(Intent.ACTION_RUN);
                        i.setClass(context, TService.class);
                        context.startService(i);
                }
        }    
}
 
二，然後再做一個service:
package com.testService;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.Handler;
import android.os.IBinder;
import android.util.Log;

public class TService extends Service {
        /**
        * 創建Handler對象，作為進程傳遞postDelayed之用
         */
        private Handler objHandler = new Handler();
        private int intCounter = 0;
        private static final String TAG = "TService";
        private NotificationManager notificationManager;
       private Runnable mTasks = new Runnable() {
                public void run() {
                        intCounter++;

                        Log.i("HIPPO", "Counter:" + Integer.toString(intCounter));

                        objHandler.postDelayed(mTasks, 1000);
                }
        };

        public void onCreate() {
                Log.d(TAG, "============> TService.onCreate");
                notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                showNotification();
                super.onCreate();
        }
       
        public void onStart(Intent intent, int startId) {
                Log.i(TAG, "============> TService.onStart");
                objHandler.postDelayed(mTasks, 1000);
                super.onStart(intent, startId);
        }

        public IBinder onBind(Intent intent) {
                Log.i(TAG, "============> TService.onBind");
                return null;
        }

        public class LocalBinder extends Binder {
                public TService getService() {
                        return TService.this;
                }
        }

        public boolean onUnbind(Intent intent) {
                Log.i(TAG, "============> TService.onUnbind");
                return false;
        }

        public void onRebind(Intent intent) {
                Log.i(TAG, "============> TService.onRebind");
        }  www.2cto.com

        public void onDestroy() {
                Log.i(TAG, "============> TService.onDestroy");
                notificationManager.cancel(R.string.service_start);
                objHandler.removeCallbacks(mTasks);
                super.onDestroy();
        }

        private void showNotification() {
                Notification notification = new Notification(R.drawable.icon,
                                "SERVICE START", System.currentTimeMillis());

                Intent intent = new Intent(this, testService.class);
                intent.putExtra("FLG", 1);
                PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                                intent, 0);

                notification.setLatestEventInfo(this, "SERVICE", "SERVICE START",
                                contentIntent);
                notificationManager.notify(R.string.service_start, notification);
        }
}

三，再做一個主程序：
package com.testService;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class testService extends Activity {
       
        private Button button01;
        private Button button02;
        private int flg;
        private Intent tsIntent;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       
       
        setContentView(R.layout.main);
        button01 = (Button)findViewById(R.id.Button01);
        button02 = (Button)findViewById(R.id.Button02);
       
        tsIntent = this.getIntent();
        Bundle bundle = tsIntent.getExtras();
       
        if (bundle == null){
            flg = 1;
            DisplayToast(this,"Service Start",2);
            startService();
            finish();
        }else{
                DisplayToast(this,"Service Stop",2);
                stopService();
                finish();
        }
       
        button01.setOnClickListener(Listener01);
        button02.setOnClickListener(Listener02);
       
    }
   
    Button.OnClickListener Listener01 = new OnClickListener(){

                @Override
                public void onClick(View v) {
                        // TODO Auto-generated method stub
                        startService();
                }
           
    };
   
    Button.OnClickListener Listener02 = new OnClickListener(){

                @Override
                public void onClick(View v) {
                        // TODO Auto-generated method stub
                        stopService();
                }
           
    };
   
        private void startService() {
                Intent i = new Intent(testService.this, TService.class);
                i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                this.startService(i);
        }
   
        private void stopService() {
                Intent i = new Intent(testService.this, TService.class);
                this.stopService(i);
        }

        public static void DisplayToast(Context context , String str , int time){
                if (time == 1){
                        //短時間顯示Toast
                        Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
                }else if (time == 2){
                        //長時間顯示Toast
                        Toast.makeText(context, str, Toast.LENGTH_LONG).show();
                }
        }
}

四，最後在androidmenfest.xml中注冊一下接受廣播器和服務以及開通權限：
接收廣播器：
        <receiver android:name=".StartBroadcastReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
            </intent-filter>
        </receiver>

服務：
         <service android:name=".TService"
            android:label="TService"
            android:icon="@drawable/icon"
            android:enabled="true"
            android:exported="true"
            android:process=":remote">
        </service>
 
復制代碼
注冊權限：
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
注意：接受廣播和服務都必須注冊在：<application>這裡注冊</application>
