本文介绍了一个Android应用中启动后台服务并使用广播接收器确保服务随设备启动而激活的方法。通过实现StartBroadcastReceiver和TService类，以及testService主程序，确保了应用能在设备重启后继续运行。

一、首先做一个监听器：

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、然后再做一个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 { /** * 创建Handler对象，作为进程传递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"); } 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、再做一个主程序：

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){ //短时间显示Toast Toast.makeText(context, str, Toast.LENGTH_SHORT).show(); }else if (time == 2){ //长时间显示Toast Toast.makeText(context, str, Toast.LENGTH_LONG).show(); } }}

四、最后在androidmenfest.xml中注册一下接受广播器和服务以及开通权限：

1、接收广播器：

2、服务：

3、注册权限：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

注意：接受广播和服务都必须注册在：<application>这里注册</application>
