Android服务在应用程序被终止后停止

我想创建一个

服务

，即使在任务管理器关闭应用程序时也能运行。我已经创建了一个服务，然后记录了一条消息来检查它是否正在运行，我注意到它只有在应用程序正在运行或在前台时才能工作

服务类别：

public class CallService extends Service {

    private final LocalBinder mBinder = new LocalBinder();
    protected Handler handler;

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

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

    @Override
    public void onCreate() {
        super.onCreate();

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("TESTINGSERVICE", "Service is running");
    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {
   ...
   startService(new Intent(this, CallService.class));

从我的主要活动开始服务：

public class CallService extends Service {

    private final LocalBinder mBinder = new LocalBinder();
    protected Handler handler;

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

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

    @Override
    public void onCreate() {
        super.onCreate();

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("TESTINGSERVICE", "Service is running");
    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {
   ...
   startService(new Intent(this, CallService.class));

清单

<application>
   ...
   <service
      android:name=".activities.services.CallService">
   </service>
</application>

...

我需要做什么改变？谢谢，各位

在您的服务中，添加以下代码

@Override
public void onTaskRemoved(Intent rootIntent){
    Intent restartServiceIntent = new Intent(getApplicationContext(), this.getClass());
    restartServiceIntent.setPackage(getPackageName());

    PendingIntent restartServicePendingIntent = PendingIntent.getService(getApplicationContext(), 1, restartServiceIntent, PendingIntent.FLAG_ONE_SHOT);
    AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    alarmService.set(
    AlarmManager.ELAPSED_REALTIME,
    SystemClock.elapsedRealtime() + 1000,
    restartServicePendingIntent);

    super.onTaskRemoved(rootIntent);
 }

我的手机太残忍了，在应用程序关闭的那一刻，前台服务就被扼杀了。我试过了，但也失败了：（使用Oppo A3S）
