Answer 1

Add marker to desired position in map then call this function with that marker

private void dropPinEffect(final Marker marker) {
        final Handler handler = new Handler();
        final long start = SystemClock.uptimeMillis();
        final long duration = 1500;

        final Interpolator interpolator = new BounceInterpolator();

        handler.post(new Runnable() {
            @Override
            public void run() {
                long elapsed = SystemClock.uptimeMillis() - start;
                float t = Math.max(
                        1 - interpolator.getInterpolation((float) elapsed
                                / duration), 0);
                marker.setAnchor(0.5f, 1.0f + 14 * t);

                if (t > 0.0) {
                    // Post again 15ms later.
                    handler.postDelayed(this, 15);
                } else {
                    marker.showInfoWindow();

                }
            }
        });
    }
