Android: Update Listview after Thread loads data from the net

Question

1. I like that my GUI appears immediately when the user starts the app.
2. Then some data (text, pictures) gets loaded in the background (like YouTube app).

Answer 1

Just found it myself while reading this thread and trying around.

Short: AsyncTask's method onProgressUpdate can touch the view: http://developer.android.com/reference/android/os/AsyncTask.html#onProgressUpdate(Progress...)

Background: I needed to call requery on my cursor so a ListView kept being updated while the task fills the database. The requery call made in doInBackground failed with the mentioned CalledFromWrongThreadException but same code in onProgressUpdate works.
