J'ai essayé le programme comme indiqué dans le livre OpenGL ES2 pour Android, mais il ne fonctionne pas !!
J'ai testé dans Odroid E, samsung s3, samsung y, samsung star !!
the gl version suported returns 2, but i get

Voici mon code
public class Main_OGLT1 extends Activity {
MySurface mGLSurfaceView;
private boolean renderSet;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mGLSurfaceView = new MySurface(this);//(this); //instantiation
ActivityManager actMan = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
ConfigurationInfo mConfigInfo = actMan.getDeviceConfigurationInfo();
boolean isES2Compat = (mConfigInfo.reqGlEsVersion >= 0x20000);
Log.e("oGl-es v",mConfigInfo.getGlEsVersion()+":"+ mConfigInfo.reqGlEsVersion);
if(isES2Compat){
renderSet = true;
Log.e("render","set");
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main__oglt1, menu);
return true;
}
@Override
protected void onResume()
{
// The activity must call the GL surface view's onResume() on activity onResume().
super.onResume();
mGLSurfaceView.onResume();
}
@Override
protected void onPause()
{
// The activity must call the GL surface view's onPause() on activity onPause().
super.onPause();
mGLSurfaceView.onPause();
}
}
La classe MySurface:
public class MySurface extends GLSurfaceView{
public MySurface(Context context) {
super(context);
// TODO Auto-generated constructor stub
setEGLContextClientVersion(2);
setRenderer(new MyTestRenderer(getContext()));
}
}
Le problème est avec glSurfaceView, car il ne s'exécute pas sur le thread OpenGL. Le glSurfaceView devrait être sur le thread principal Android.

J'espère que cette aide.
