Android google maps cant zoom with compass active

Hee guys,

I'm currently using a sensorlistener to make my screen adjust as a compass. However I can't zoom in or out because I am constantly updating the camera when onSensorChanged is called. Is there any way to make it able to zoom?

private SensorEventListener mySensorEventListener = new SensorEventListener() {

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {
    }

    @Override
    public void onSensorChanged(SensorEvent event) {
        if(routeStarted == true)
        {
            if(event.sensor.getType() == Sensor.TYPE_ROTATION_VECTOR) {
                SensorManager.getRotationMatrixFromVector(
                        mRotationMatrix , event.values);
                float[] orientation = new float[3];
                SensorManager.getOrientation(mRotationMatrix, orientation);
                float bearing = (float) (Math.toDegrees(orientation[0]) + mDeclination);
                float tilt = 30;
                updateCamera(bearing, tilt);

            }
        }
    }
};  

private void updateCamera(float bearing, float tilt) {
        // TODO Auto-generated method stub
        LatLng post = new LatLng(mGoogleMap.getMyLocation().getLatitude(), mGoogleMap.getMyLocation().getLongitude());
        CameraPosition pos = new CameraPosition(post, 15, tilt, bearing);
        mGoogleMap.moveCamera(CameraUpdateFactory.newCameraPosition(pos));
    }

You should use the currentzoom level obtained from the map instead of the static value 15. like this:

float zoom = map.getCameraPosition().zoom;
CameraPosition pos = new CameraPosition(post, zoom, tilt, bearing);

If you want to initialise the view on 15, then do this somewhere else for example when the activity starts.
