问题已解决

Done this:

设置>权限>自动启动 然后 打开我的应用程序的 Switch,然后完成!

我在这个 link 中找到了解决方案:

代码可能对您有帮助 HourlyService class onStartCommand 方法 returns START_STICKY

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

里面Activity

 private HourlyService mHourlyService;
private ServiceConnection mServiceConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
        // We've bound to LocalService, cast the IBinder and get LocalService instance
        LocalBinder binder = (LocalBinder) iBinder;
        mHourlyService = binder.getService();
        mBound = true;
    }

    @Override
    public void onServiceDisconnected(ComponentName componentName) {
        mBound = false;
    }
};

@Override
protected void onStart() {
    super.onStart();
    // Bind to LocalService
    Intent intent = new Intent(this, HourlyService.class);
    bindService(intent, mServiceConnection, Context.BIND_AUTO_CREATE);
}

@Override
protected void onStop() {
    super.onStop();
    unbindService(mServiceConnection);
    mBound = false;
}

在某些设备(特别是小米、华为、联想)上,您需要将您的应用添加到 "protected apps" 或 "apps that are allowed to run in the background" 的列表中。如果您的应用不在列表中,Android 将不会自动重启您的 Service,即使您已从 onStartCommand() 返回 START_STICKY。这是一个 "battery saving feature" 不幸的是给开发人员带来了很多问题!

在电源管理、安全或应用下的 Android 设置中查找这些设置。

还请解释一下 "kill my app" 的含义。如果您强行关闭您的应用程序,那么 Service 将不会被 Android 重新启动。这是故意的,如果您强制关闭应用程序,它也不会在模拟器上重新启动。

您需要在服务属性里面的清单中添加"android:process=:any_name"。

例如,

      <service android:name=".MyService"
        android:process=":MyService"
        android:enabled="true"/>

下面是我的服务代码class。

public class MyService extends Service {
@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}


@Override
public void onCreate() {
    super.onCreate();
    Log.e("onCreate", "onCreate");
    Toast.makeText(AppController.getInstance(),"Created",Toast.LENGTH_SHORT).show();
}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.e("servicedestroy", "servicedestroy");
    Toast.makeText(AppController.getInstance(),"service destroy",Toast.LENGTH_SHORT).show();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Timer t = new Timer();
    t.scheduleAtFixedRate(new TimerTask() {
                              @Override
                              public void run() {

                                  new Handler(Looper.getMainLooper()).post(new Runnable() {
                                      @Override
                                      public void run() {
                                          Toast.makeText(AppController.getInstance(),"Running",Toast.LENGTH_SHORT).show();
                                      }
                                  });


                              }

                          },
            0,
            5000);

    return START_STICKY;
}

@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);
}

}
