I also tried to create a new surface from SurfaceComposerClient. Then feed the eglCreateWindowSurface with this surface just like the Bootup animation did. However, it will runtime crash because of lacking the permission of ACCESS_SURFACE_FLINGER. Seems this permission will not be granted to third-party application. So how can I setup the EGL environment without a native window? <_>
