Сервис Acceleromter не работает на Android TV Box

Question

Я разрабатываю приложение, в котором выполняются услуги Accelerometer в фоновом режиме. В этом сервисе Accelerometer я получаю данные с сервера. Но приложение отлично работает на мобильном телефоне, но оно не работает на Android TV Box. Вот код

public class AccelerometerService extends Service implements  
SensorEventListener 
    { 
public IBinder onBind(Intent intent) 
{ 
    // TODO: Return the communication channel to the service. 
    throw new UnsupportedOperationException("Not yet implemented"); 
    } 

boolean loading_data=false; 

public void onCreate() 
    { 

screenLock = ((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(
     PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG"); 

//(((Hanlder Class RUN after 1 Seocond. Update Time/Date ))))) 
    final Handler someHandler = new Handler(getMainLooper()); 
     someHandler.postDelayed(new Runnable() 
    { 
     @SuppressWarnings("deprecation") 
     @Override 
     public void run() 
     { 
     someHandler.postDelayed(this, 2000); 

     //  total_sec_count=obj.Get_Count_Val(); 

     // total_sec_count+=2; 

     //obj.Set_Screen_count(total_sec_count); 

     // showtoast("ddd = "+total_sec_count); 
     // Log.e("count val = ",""+total_sec_count); 


     // showtoast(("lat/long = "+SingletonClass.getInstance().Get_Latitude()+":"+SingletonClass.getInstance().Get_Longitude())); 
     } 
    }, 2000); 

}

Где y ou инициализировать объект датчика, вы должны убедиться в его наличии и произвести надлежащую ошибку, если это не так:

SensorManager sensorManager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE); 
Sensor accelerometer = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); 
if (accelerometer != null) 
{ 
    // Device has Accelerometer 
}
