GLES20RecordingCanvas

public class GLES20RecordingCanvas extends GLES20Canvas
An implementation of a GL canvas that records drawing operations. This is intended for use with a DisplayList. This class keeps a list of all the Paint and Bitmap objects that it draws, preventing the backing memory of Bitmaps from being freed while the DisplayList is still holding a native reference to the memory.
