Hello, 
I was reading through this post http://findnerd.com/list/view/Problem-in-Google-map-rotation-in-Android/23827/
and was searching for a solution of rotation issue. I want to implement same as in uber app. https://drive.google.com/open?id=1J3jLEJb7_tj6fBOFpaXODYE1fMCBy_TJ

If anyone have solved this then please reply here.

I am using following code for rotation and animation: 

public void animateMarker(final Marker marker, final LatLng toPosition) {

    final Handler handler = new Handler();
    final long start = SystemClock.uptimeMillis();

  Projection proj = mGoogleMap.getProjection();

  Point startPoint = proj.toScreenLocation(carMarker.getPosition());

  final LatLng startLatLng = proj.fromScreenLocation(startPoint);

    final long duration = 800;//500

    final Interpolator interpolator = new LinearInterpolator();

    handler.post(new Runnable() {
        @Override
        public void run() {

            long elapsed = SystemClock.uptimeMillis() - start;
            float t = interpolator.getInterpolation((float) elapsed / duration);

            double currlat = t * toPosition.latitude + (1 - t) * startLatLng.latitude;
            double currlng = t * toPosition.longitude + (1 - t) * startLatLng.longitude;

            LatLng latlng= new LatLng (currlat, currlng);

            marker.setPosition(latlng);

            if (t < 0.7) {
                // Post again 16ms later.
                handler.postDelayed(this, 16);
            } else {

            }
        }
    });
}

private void rotateMarker(final Marker marker, float fromRotation, final float toRotation) {

    if (!isMarkerRotating) {
        final Handler handler = new Handler();
        final long start = SystemClock.uptimeMillis();
        final float startRotation = fromRotation;
        final long duration = 1000;

        final Interpolator interpolator = new LinearInterpolator();

        handler.post(new Runnable() {
            @Override
            public void run() {
                isMarkerRotating = true;

                long elapsed = SystemClock.uptimeMillis() - start;
                float t = interpolator.getInterpolation((float) elapsed / duration);

                float rot = t * toRotation + (1 - t) * startRotation;

                marker.setRotation(-rot > 180 ? rot / 2 : rot);

                if (t < 1.0) {
                    // Post again 16ms later.
                    handler.postDelayed(this, 16);
                } else {
                    isMarkerRotating = false;
                }
            }
        });
    }
}
