Android ICS SurfaceHolder.lockCanvas () failed internally and returns null

Question

I got a sample project of BasicGLSurfaceView and modified it to simulate the problem that we are facing in our project.
I changed the action to use luckCanvas API for SurfaceHolder from GLSurfaceView:

public class BasicGLSurfaceViewActivity extends Activity implements OnClickListener { //Added a on click listener to draw some text on the view ...... @Override protected void onCreate(Bundle icicle) { super.onCreate(icicle); mView = new BasicGLSurfaceView(getApplication()); mView.setOnClickListener(this); // adding the on click listener setContentView(mView); } ............. @Override public void onClick(View arg0) { Toast.makeText(this, "OnClicked", Toast.LENGTH_SHORT).show();//Toast message AsyncTask asyncTask = new AsyncTask(){ @Override protected Void doInBackground(Void... params) { Canvas lockCanvas = mView.getHolder().lockCanvas(); // Trying to get canvas to draw something if(lockCanvas!=null){ Paint paint = new Paint(); paint.setColor(Color.RED); paint.setTextSize(36.0f); lockCanvas.drawText("Hello usgin locked canvas", 10, 50, paint); mView.getHolder().unlockCanvasAndPost(lockCanvas); } return null; } }; asyncTask.execute(); } } 

If you check this code, you will see that lockCanvas is always null, and the following error is displayed inside logcat:

But this code works in GingerBread without any problems.
Could you explain what changes in the ice cream sandwich lead to this problem or what would be a workaround to solve this problem?

In addition, I also get the following error:

Thank you very much.
