Background Service not working on MIUI 9.6 Redmi 4x

Question

I have been searching in the entire web understanding why my background service is not working. When I close the application the service is killed without being called back from the Brodcast Receiver. This guide : https://www.quora.com/How-do-I-keep-an-app-running-in-the-background-in-MIUI shows three different methods and none of them is working for me. I'm sure that the application is perfectly working because it works fine with the emulator, same API 24, and it worked with a huawei aswell, again same API.

    android:name="com.arvi.neverendingbackgroundservice.SensorService"

Service

public class SensorService extends Service {
    private Context ctx;
    TimerCounter tc;
    private int counter = 0;
    private static final String TAG = SensorService.class.getSimpleName();

    public SensorService() {

    }

    public SensorService(Context applicationContext) {
        super();
        ctx = applicationContext;
        Log.i(TAG, "SensorService class");
    }

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

    @Override
    public void onCreate() {
        super.onCreate();
        Log.i(TAG, "onCreate()");

        tc = new TimerCounter();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        super.onStartCommand(intent, flags, startId);
        Log.i(TAG, "onStartCommand()");


        tc.startTimer(counter);
        return START_STICKY;
    }

    @Override
    public void onDestroy() {
        Log.i(TAG, "serviceOnDestroy()");

        super.onDestroy();

        Intent broadcastIntent = new Intent(getApplicationContext(),SensorRestartBroadcastReceiver.class);
        sendBroadcast(broadcastIntent);
        tc.stopTimerTask();
    }

    @Override
    public void onTaskRemoved(Intent rootIntent) {
        Log.i(TAG, "serviceonTaskRemoved()");



        // workaround for kitkat: set an alarm service to trigger service again
        Intent intent = new Intent(getApplicationContext(), SensorService.class);
        PendingIntent pendingIntent = PendingIntent.getService(this, 1, intent, PendingIntent.FLAG_ONE_SHOT);
        AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarmManager.set(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime() + 5000, pendingIntent);

        super.onTaskRemoved(rootIntent);

    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        Log.i(TAG, "onLowMemory()");
    }
}
