I want to develop an application with some advance features like shake feature, orientation of images, zoom in/out, scrolling, etc. For instance, the user can shake the phone in order to erase an entered text. Also, by rotating the phone clockwise or anti-clockwise, the orientation of the underlying images will change.
我如何这样做?

When the phone detects an orientation change, Android will destroy and recreate your application. There are lifecycle methods (see http://developer.android.com/reference/android/app/Activity.html) that are called that allow you to save and restore your application s current state.
