Android 为什么系统进程第二次终止我的服务？

我有一个带有服务的android应用程序。第一次运行该服务时效果很好，但第二次在同一个模拟器中运行时，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，每次我运行正常时，我都必须销毁机器并重新创建它。原因是什么

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)){

        }
    }
}

谢谢。

活动结束后，您是否在活动中停止服务？因为第二次运行（从IDE）会重新安装应用程序，而旧的应用程序必须停止…服务始终在后台运行，等待事件屏幕打开。另外，在第二次启动应用程序之前，我试图手动停止服务，但仍然存在相同的问题…还抛出此错误：04-17 21:51:07.552:I/ActivityManager（60）：强制停止包es.myapp uid=10034 04-17 21:51:07.552:W/ActivityManager（60）：计划在5000ms 04-17 21:51:07.562:I/进程（60）：发送信号中重新启动崩溃的服务es.myapp/.PhoneService。PID:298 SIG:9I在手机上测试了该应用程序，但未运行，原因是该应用程序安装在SD卡上，而不是安装在手机上，SD卡是在启动完成后安装的，因此未收到事件。谢谢你的回答
