我尝试了 OpenGL ES2 for Android 中所示的程序，但它不起作用！
我在 Odroid E、samsung s3、samsung y、samsung star 中测试过！！
the gl version suported returns 2, but i get

下面是我的代码
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();
}
}
MySurface 类：
public class MySurface extends GLSurfaceView{
public MySurface(Context context) {
super(context);
// TODO Auto-generated constructor stub
setEGLContextClientVersion(2);
setRenderer(new MyTestRenderer(getContext()));
}
}
