The error you are getting is because of accessing UI elements from background thread.

AsyncTask is a Thread pool based api that runs your task in a seperate thread ,but your UI part runs in a thread usually called UI thread, to update any changes to ui put the logic onPostExecute()

NOTE: Use okhttp to get consistent http api, it also supports http2.Their github wiki is very helpful, check here for examples.
