Android Servis Arka Planda Çalışmıyor

05.08.2017 - 06:48

Merhaba Arkadaşlar Android servis oluşturdum. Bu servis konum güncellenince  api çağırıyor ve veri kaydediyor. Uygulama ön planda olunca sorun yok ancak arka plana alınca servisim çalışmıyor . Sebebi ne  olabilir ? Servisim aşağıdaki gibidir.

 


public class VehicleGPSTrackerService extends Service {

    private LocationListener listener;
    private LocationManager locationManager;
    boolean gps_enabled = false;

    }

    public String getCurrentDate()
    {
        Calendar c = Calendar.getInstance();
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String strDate = format.format(c.getTime());

        return strDate;
    }

    private String getDeviceImei() {

        mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        String deviceid = mTelephonyManager.getDeviceId();
        Log.d("msg", "DeviceImei " + deviceid);
        return deviceid;
    }

}

Bu servisi de şu şekilde çağırıyorum

 Intent i =new Intent(MainActivity.this,VehicleGPSTrackerService.class);
                startService(i);

manifast.xml dosyası da şu sekildedir

 <service
            android:name=".VehicleGPSTrackerService"
            android:enabled="true"
            android:exported="false"/>
