Question

我有一个带有服务的Android应用程序。我第一次运行该服务时效果很好，但是当我在同一个模拟器中第二次运行时会收到此消息。

04-17 18:27:15.808: D/PackageManager(61):   Services: es.myapp.PhoneService

我在模拟器上有足够的内存因此，每次运行良好时，我必须销毁机器并重新创建它。是什么原因？

代码如下：

public class PhoneService extends Service{

    private final IBinder mBinder = new LocalBinder();  

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

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    @Override
    public void onCreate(){

        this.setForeground(true);

        try {
            IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
            filter.addAction(Intent.ACTION_SCREEN_OFF);
            filter.addAction(Intent.ACTION_USER_PRESENT);
            BroadcastReceiver mReceiver = new ScreenReceiver();
            registerReceiver(mReceiver, filter);
       } catch (Exception e) {

       }    
    }

       @Override
        public void onDestroy() {
        }


       @Override
       public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStart(intent, startId);
            return START_STICKY;
    }
}





public class Receiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {

            Intent serviceIntent = new Intent();
            serviceIntent.setAction("es.myapp.PhoneService");
            context.startService(serviceIntent);
    }
}




public class ScreenReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {         

        if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)){
            Intent photoIntent = new Intent(context, TakePhoto.class);
            photoIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(photoIntent);
        }
        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)){

        }
        if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)){

        }
    }
}
