First step to add support for Choreographer based animations. The Choreographer_Delegate avoid using a handler so the animation callbacks can be called on-demand (by using doFrame). This allows things like frame by frame animation or selecting a specific frame, and doesn't need a separate thread to run. The CL also changes the System and SystemClock implementations to allow to set specific times. Because animations heavily rely on the system time, this allows controlling it. It can also be useful to ensure that the rendering produces a deterministic result when using controls like the Calendar widget. Change-Id: Iff221d2698a82075cafbb60f341be01741f7aa13
Layoutlib is a custom version of the android View framework designed to run inside Eclipse. The goal of the library is to provide layout rendering in Eclipse that are very very close to their rendering on devices. None of the com.android.* or android.* classes in layoutlib run on devices.
