It's hard to see what's going on here because you didn't post the
outer part -- is this an activity onCreate? Looks like you're
accessing your string field before the setContentView.
This is loosely related to your question but you might consider that:
- you're not supposed to do the network fetching part in the main
thread (you don't want to block it and your app will ANR)
- if you move your code to another thread, you can only access the UI
from the main thread.
You might want to change your operation order: set the content view &
get the views, post a thread that will get the data and update your UI
when done.
