Answer 1

Caused by: android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original 
        thread that created a view hierarchy can touch its views.

You are setting the text of the textview from a background thread. You have to do it on the main (UI) thread. Change your AsyncTask to simply build the string in doInBackground() and update the textview in onPostExecute() instead.
