Question

I have three views in my app and I would like to be able to hide them and bring them back selectively. I have tried using the following triggered by a button click event:

 if(SurfaceView().isShown()==true){
            SurfaceView().setVisibility(View.INVISIBLE);
        }else if(!SurfaceView().isShown()){
            SurfaceView().setVisibility(View.VISIBLE);
        }

However this usually freezes up the views and then closes the app with no errors except the following :

NvRmChannelSubmitt: NvError_IoctlFailed with error code 14

EDIT: the view that Im referring to is actually the _glsurfaceview in the renderactivity from min3d

public class RendererActivity extends Activity implements ISceneController
{
public Scene scene;
protected static GLSurfaceView _glSurfaceView;

My main activity extend RenderActivity

EDIT: added logcat dump

The only things showing up upon the closing are these

03-02 15:57:00.338: I/Min3D(28364): Renderer.onSurfaceChanged()
03-02 15:57:00.355: D/(28364): NvRmChannelSubmit: NvError_IoctlFailed with error code 14

Looks like you might have a copy/paste typo in your code. Are you trying to show the glSurfaceView if the SurfaceView is invisible? If so, try this:

if( SurfaceView().isShown() )
{
  glSurfaceView().setVisibility(View.GONE);
}
else if ( !SurfaceView().isShown() )
{
  glSurfaceView().setVisibility(View.VISIBLE);
}
