screenshot in android

Question

The following is the code I am using to take a screen shot using GLSurfaceView. But I dont know why the onDraw() method in the GLSurfaceView.Renderer Class is not being call

Answer 1

Although you create the surfaceview, you don't set it to be the current contentview

setContentView(mGLView);

Also, you are creating the screenshot every single frame, which is very inefficient and probably not what you'll want..
