Apps Need help: start a new activity (using 3d rotate)

[ryan2010]

Dear all, currently i'm running an application. It requires that when you start a new activity, a 3D rotating effect should be shown first. For example, you touch the icon "settings", then a rotating effect like the above picture should be shown first, and then the "settings" is emerged.

Does any one knows how to implement this?

There are a couple of ways. You can "fake" it with a 2D animation or you can use OpenGL to create an actual object to rotate. Either one is a fair bit of work.
