android 后台service开机自启动

比如说，新闻客户端，IM聊天工具，关机开机之后，需要后台的服务启动，来收到最新的推送或者消息。或者这个service要做其他事情，总之要能够开机自启。每当服务启动的时候，我们启动一个通知栏，代码如下：

public class MyService  extends Service{

	@Override
	public IBinder onBind(Intent arg0) {
		// TODO Auto-generated method stub
		return null;
	}
	
	@Override
	public void onCreate() {
		// TODO Auto-generated method stub
		super.onCreate();
		Notification notification = new Notification(R.drawable.ic_launcher, "myService", System.currentTimeMillis());
		Intent notificationIntent  = new Intent(this,MainActivity.class);
		PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);
		notification.setLatestEventInfo(getApplicationContext(), "this is title ", "this is content ", pendingIntent);
		startForeground(1, notification);
		Log.e("myService", "onCreate");
		
	}

}

界面很简答，start这个service就行，主要是设置权限：

 <service android:name = ".MyService">
            </service>
            
          <receiver android:name=".BootBroadcastReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
                <category android:name="android.intent.category.HOME" />
            </intent-filter>
        </receiver>

用一个广播来接收，开机的Intent，收到这个广播之后，直接启动service就行了。

public class BootBroadcastReceiver extends BroadcastReceiver {
    static final String action_boot="android.intent.action.BOOT_COMPLETED"; 
 
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(action_boot)){ 
            Intent intentService = new Intent(context, MyService.class);
    	
    		context.startService(intentService);
        }
 
    }
 
}

好了，代码已经完成了，除了主Activity，你自己去启动就可以了，记得要在安全中心里设置，这个应用开机自启哦。
