This is a very common effect, however the Android framework only provides the slide in animation. This is how I implement all the sliding transition animation. There’s in total 4 XMLs to define the animation, and with the use of overridePendingTransition() in appropriate location you can implement this easily.

I believed that a lot of iPhone, iPad and iPod touch owners are excited about iOS 6, which is released a while ago, and already made the upgrade. There are couple of cool new features, however, some people think it is a mess. The most obvious example is the Maps app, which the good old Google Maps is replaced with a half-baked Apple Maps.
