android service中intentfilter,android – IntentFilter的Intend.ACTION_PACKAGE_REPLACED的BroadcastReceiver...

我正在尝试设置一项服务,以检查何时在设备中安装了新的活动更新.我已经在应用程序活动中完成了这项工作,在清单中声明Broadcastreceiver并且它完美地工作.

但是,当我尝试在服务中运行该接收器并动态声明它时,我的onReceive永远不会被调用.这是我的服务代码：

public class UpdateService extends Service {

private static String mPackage = "com.my.package";

private static String mActivityName = "myActivity";

private BroadcastReceiver mUpdateReceiver;

@Override

public void onCreate() {

super.onCreate();

mUpdateReceiver = new BroadcastReceiver() {

@Override

public void onReceive(Context context,Intent intent) {

Log.d("mTag","In the BroadcastReceiver onReceive()");

if (intent.getAction().equalsIgnoreCase(Intent.ACTION_PACKAGE_REPLACED)) {

// Log that a new update is has been found

Log.d("mTag","New version of the app has been installed.");

Log.d("mTag","Intent data: " + intent.getDataString());

Log.d("mTag","My package: " + mPackage);

}

}

};

Log.d("mTag","In the service onCreate() method.");

IntentFilter filter = new IntentFilter();

filter.addAction(Intent.ACTION_PACKAGE_REPLACED);

filter.addAction(Intent.ACTION_PACKAGE_REMOVED);

filter.addAction(Intent.ACTION_PACKAGE_ADDED);

registerReceiver(mUpdateReceiver,filter);

}

@Override

public int onStartCommand(Intent intent,int flags,int startId) {

Log.d("mTag","UpdateService started");

return Service.START_STICKY;

}

@Override

public void onDestroy() {

super.onDestroy();

unregisterReceiver(mUpdateReceiver);

Log.d("mTag","Service destroyed");

}

@Override

public IBinder onBind(Intent arg0) {

return null;

}

}

调用服务onCreate(),这告诉我该服务已启动并正在运行.但是,在通过adb安装和替换某些应用程序之后,BroadcastReceiver中的所有日志都没有调用onReceive()方法.

这是我的MainActivity：

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

startService(new Intent(this,UpdateService.class));

}

}

你们有什么想法为什么onReceive()没有被调用？

谢谢.
