Android TextView Does Not Display Returned Data

Android TextView Does Not Display Returned Data

I'm building an android app which uses AsyncTask and JSOUP to scrape some
data off a webpage (in this case the title tag from google.com) and
display it as a textview. When I attempt to debug the app I'm getting a
value returned from google containing the title tag (shown as doc below)
however it does not seem to print on the screen when I execute the
application.
P.S.
When debugging it finally arrives in the for loop and just repeats (as it
should) but does not display any data.
