Why is my map not initializing after receiving location permission?

Question

The first time a user opens my MapsActivity they are asked for location permission. It should then start my satellite view map with markers at different locations. However, it opens a generic google maps without my markers, but if you then exit the activity and start it again once location permissions have already been granted, it works fine. I'm pretty sure it's not calling my initMap() function and hence not calling the onMapReady(GoogleMap, googleMap) function where the map is set to satellite view and the markers are added. I'm pretty sure that in my onRequestPermissionsResult() function it is not calling the initMap() function when it should, but I don't know why?

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleMap.OnMapClickListener {

    @Override
    public void onMapReady(GoogleMap googleMap) {
        Toast.makeText(this, "Map is Ready", Toast.LENGTH_SHORT).show();
        mMap = googleMap;
        Log.d("map", mMap.toString());
        mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        if (mLocationPermissionsGranted) {
            Log.d("map", "location permission granted");
            getDeviceLocation();
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                    != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this,
                    Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                return;
            }
            mMap.setMyLocationEnabled(true);
            mMap.getUiSettings().setMyLocationButtonEnabled(false);
            this.mMap.setOnMapClickListener(this);
            init();
        }

                    MarkerOptions options = new MarkerOptions().title(children.getKey()).position(coords);
                    mMap.addMarker(options);

Answer 1

Added:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

to my Manifest and it worked
