Class SurfaceTextureWrapper


public class SurfaceTextureWrapper extends Object
A wrapper for a SurfaceTexture that tracks whether the texture has been released.

The engine calls SurfaceTexture.release on the platform thread, but updateTexImage is called on the raster thread. This wrapper will prevent updateTexImage calls on an abandoned texture.
