Answer 1

All your setText, Toast, etc... actions should be done in the UI thread.

For instance, stuff like: friendLabel.setText(name);

In order to fix that, I would suggest you to do that inside the onPostExecute:

    @Override
    protected void onPostExecute(JSONArray result) {
        updateUI();// Do whatever you want here
    }

From: http://developer.android.com/reference/android/os/AsyncTask.html

onPostExecute(Result), invoked on the UI thread after the background computation finishes. The result of the background computation is passed to this step as a parameter.
