回答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();

                }
            }
        });
    }

Check this thread and this thread

Android has overlay markers (see ItemizedOverlay) that make it easy to add images to maps, BUT note that, in my experience at least, animated images do not work when added to overlays.

But to be honest, you should remember that it's Android, and copying every little feature from iOS is unnecessary. Google Maps on Android doesn't use a pin marker, it uses a static blue spot - I'd say it's best to replicate that and remember your users are Android users, not iOS users - they want consistency across Android apps
