Question

Answer 1

A little more details

Problem:

• UI elements can be modified in the UI thread only. One exception is their postInvalidate() method (and its variants) that can be executed from outside the UI Thread
• the error you receive is caused by an attempt to modify a UI element (a View) from outside the UI thread - doInBackground() runs on a background thread

Solution:

• modify the views in the onPostExecute() method - it runs on the UI thread
• obtain a reference to the an Activity and use its runOnUiThread(Runnable) method
• depending on the modification use one of the View's post...() methods
