Problem with Toast in AsyncTask method call

Question

The code in the doInBackground() method runs on its own thread so you cannot access any UI element from there directly as they are running on the UI thread.

So you got two options.

2. You handle UI stuff in the onProgressUpdate() method which also runs on the UI thread. You can trigger this method from within doInBackground() by calling publishProgress().
