You can pass an instance of your activity in the constructor of your AsyncTask. But be sure to call the methods of activity only inside onPreExecute() and onPostExecute() methods, becuase they run on the UI Thread.

If you want to call some activity code while doInBackground(), then you should create a Handler and pass it to the AsyncTask, because you can not modify the ui from non UI thread.
