i'm developing an application that uses Google Maps to update the location. So far, i have had only one issue and that is of access fine location permission. This is my Manifest file.

This is my IntentService through which i'll pass the control over to my service class.
public class MyLocationUpdate extends IntentService {
double latitude,longitude;
AppLogic app = new AppLogic();
HelpMe activity;
IETrackerDTO iedto= new IETrackerDTO();
public MyLocationUpdate() {
super("MyLocationUpdate");
}
@Override
protected void onHandleIntent(Intent intent) {
Log.d("Inside", "Intent Service");
/*IETrackerDTO ide = intent.getExtras().("currentUser");*/
ScheduledThreadPoolExecutor s = new ScheduledThreadPoolExecutor(1);
s.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
LocationFinder gps;
Log.d("Calling other service", "Calling other service");
gps = new LocationFinder(MyLocationUpdate.this);
latitude = gps.getLatitude();
longitude = gps.getLongitude();
Log.d("Location", latitude + " " + longitude);
updateLocation();
toast();
}
}, 0, 10, TimeUnit.SECONDS);
}
public void toast() {
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "Lat: " + latitude + " long:" + longitude, Toast.LENGTH_SHORT).show();
}
});
}
This is my Service class that updates the lat long of the user on a timely basis

Everything is running just fine except for the fact that compiler asks for location permission and without that the control doesn't passes to the service class method
