android – OPENGL ES不工作：否当前上下文

我试过这个程序,如OpenGL ES2 for Android所示,但它不工作！

我已经在Odroid E测试了,三星s3,三星y,三星星！

the gl version suported returns 2,but i get
11-22 15:09:45.804: E/oGl-es v(9047): 2.0:131072

以下是我的代码

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()));
    }

 }

解决方法

问题在于glSurfaceView,因为它不会在OpenGL线程上运行. glSurfaceView应该在主要的android线程上.

希望这个帮助.
