PrimaryDashBoard, где я использую LocatinListener и извлекаю местоположение из сервиса
public class PrimaryDashboard extends AppCompatActivity implements LocationListener {
public LatLng myLatLng=new LatLng(0.0,0.0);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_primary_dashboard);
try {
Intent i = new Intent(this, LocationManager.class);
startService(i);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onLocationChanged(Location location) {
myLatLng=new LatLng(location.getLatitude(),location.getLongitude());
}
@Override
public void GPSDisabled(String errorMessage) {
}
@Override
public void GPSEnabled() {
}
}
Вот LocationListner
public interface LocationListener {
public void onLocationChanged(Location location);
public void GPSDisabled(String errorMessage);
public void GPSEnabled();
}
Вот мой сервис, где я хочу инициализировать LocationListner и хочуобновить значения местоположения из списков

Эта строка кода создает мне проблему, потому что она хочет контекст действия, когда он не будет службой, и я передаю действие. Контекст работает отлично.
this.locationUpdate = (LocationListener) getApplicationContext ();
