Callback after moveCamera on Google Maps

Question

I have a Pageview that, in one of its Fragments, houses a Mapview with a map in "Lite" mode. Clicking on this map, a second Activity is launched (startActivityForResult) which consists of a complete map, where it is possible to mark a particular location. In the onActivityResult() from Fragment, I select the camera for the position marked on the full map.

I know there is a time until the map is loaded on the specified position and zoom, so I created a spinner on the map with the attribute "Gone" in visibility. When in the onActivityResult, change this attribute dynamically to Visible.

Problem

At some point, I need to inform you that the spinner should get "Gone" again. The question is: where?

What I’ve already tried

I tried to implement some Googlemaps interfaces such as OnMapLoadedCallback and OnMapReadyCallback. OnMapReadyCallback is still called, but not when I want, after moving the camera.

public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        /*Prevent null pointer when user kill the second activity without having results
          Requestcode is not being checked because there is no more than one request for "startActivityForResults"
        */
        if(data != null) {
            map.clear();
            pbStaticMap.setVisibility(View.VISIBLE);
            Double latitude;
            Double longitude;

            latitude = (Double) data.getExtras().get("lat");
            longitude = (Double) data.getExtras().get("long");

            this.markPosition = new LatLng(latitude, longitude);


            map.addMarker(new MarkerOptions().position(markPosition));
            map.moveCamera(CameraUpdateFactory.newLatLngZoom(markPosition, 15));
        }
    }


map.setOnMapLoadedCallback( new GoogleMap.OnMapLoadedCallback() {
        @Override
        public void onMapLoaded() {
            pbStaticMap.setVisibility(View.GONE);
            Log.d("MapBorba","->>> chamou onMapLoaded ( NEW CALLBACK)");
        }
    });

You can use the interface OnCameraChangeListener, which is called every time there is a movement on the map. Inside this callback, you check the visibility of your Spinner just not to change his visibility at all times without need:

seuMapa.setOnCameraChangeListener(new OnCameraChangeListener() {
    @Override
    public void onCameraChange(CameraPosition pos) {
        if (seuSpinner.getVisibility == View.VISIBLE){
            seuSpinner.setVisibility(View.GONE);
        }       
    }
});
