(Welcome to join the android technology exchange QQ group: 209796692) Create an OpenGL ES Environment To use opengles painting in your Android app, you must create a view as a container. The most direct way isGLSurfaceViewAndGLSurfaceView.RendererA class is derived.GLSurfaceViewAs the container where OpenGL is drawn, the actual drawing action is inGLSurfaceView.Renderer.

default clear color is black if you want to specify a different color, Can call Glclearcolor also we need to know that because OpenGL is a state machine, all of its settings OpenGL will be preserved. So for Glclearcolor, the best way to call it is to put it in the initialization method, because it will only be called once if it is placed in display, OpenGL will

operating system doesn't provide OpenGL at all? There is an open source project called Mesa, which has been written in C for an OpenGL implementation, and the latest Mesa 7.0 has implemented the various functions specified in the OpenGL 2.1 standard. Download Mesa's code and compile it to get the latest version of OpenGL
