    Happens when you make a network call on the main UI thread of the Android application which results in a UI freeze until the network call is complete and the response is received. Instead, execute the network calls in the background: use AsyncTask.

    An alternative for just getting rid of the Exception is use StrictMode.ThreadPolicy to force execute on main thread.

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
