Description Máté Rédecsi 2013-11-06 06:53:10 UTC
I'm trying to use GLSurfaceView with a custom config chooser (to enable multisampling). In the constructor of my class (derived from GLSurfaceView) I call the following:

   SetEGLContextClientVersion (2);
   SetEGLConfigChooser (new MultisampleConfigChooser ());
   SetRenderer (new OpenGLRenderer (context, this));

where MultisampleConfigChosser is my implementation of Android.Opengl.GLSurfaceView.IEGLConfigChooser and OpenGLRenderer is my renderer class (implemented GLSurfaceView.IRenderer).

ChooseConfig method of the MultisampleConfigChooser class doesn't fire at all.

It can be reproduced with the "GLNativeES20" sample. Just add a custom configchooser into that application.

Hi Máté,

how does your chooser class look like?

I tried to create an empty chooser class and put it to GLNativeES20 sample and it is reached when I run the app on device.

My empty chooser class looks like this:

using System;
using Javax.Microedition.Khronos.Egl;

namespace GLNativeES20
	class MyChooser : Java.Lang.Object, Android.Opengl.GLSurfaceView.IEGLConfigChooser
		public EGLConfig ChooseConfig (IEGL10 egl, EGLDisplay display)
			Console.WriteLine ("choose config called");
			return null;

Hopefully that will help you.

@Mate, Does comment#3 helps you? Are you still getting same behavior?
Comment 5 Máté Rédecsi 2013-11-22 05:18:20 UTC

Thank you very much guys it solved my problem. I don't really know what was the problem with my chooser class, but I rebuilt it with the base of your code and it works perfectly.
