Mapbox shows wrong current location in android - mapbox

Question

I am using Mapbox sdk for android.
I want to get current location,and i am also getting,but the problem is:
I am getting wrong current location,which is near Nigeria.
can anyone help me to get perfect location??
here is my gradle file's details:
android {

please help me to get user location.
Help is appreciated,i referred a lot of questions but didnt get any solution.
than also,suggest any help in reffering questions too.

Answer 1

I Solved it by making few changes in methods initializeLocationEngine() and enableLocationPlugin()
Here are the modified methods for answer:
private void enableLocationPlugin() {
// Check if permissions are enabled and if not request
if (PermissionsManager.areLocationPermissionsGranted(this)) {
initializeLocationEngine();
locationPlugin = new LocationLayerPlugin(mapView, map, locationEngine);
locationPlugin.setLocationLayerEnabled(true);
locationPlugin.setCameraMode(CameraMode.TRACKING);
locationPlugin.setRenderMode(RenderMode.COMPASS);
getLifecycle().addObserver(locationPlugin);
Log.e(TAG, "enableLocationPlugin:Permission Granted" );
} else {
permissionsManager = new PermissionsManager(this);
permissionsManager.requestLocationPermissions(this);
Log.e(TAG, "enableLocationPlugin:Permission Not Granted" );
}
}
private void initializeLocationEngine() {
locationEngine = new LocationEngineProvider(this).obtainBestLocationEngineAvailable();
locationEngine.setPriority(LocationEnginePriority.HIGH_ACCURACY);
locationEngine.addLocationEngineListener(this);
locationEngine.activate();
Location lastLocation = locationEngine.getLastLocation();
if (lastLocation != null) {
setCameraPosition(lastLocation);
} else {
locationEngine.addLocationEngineListener(this);
}
}
