Answer 1

Can't create handler inside thread that has not called Looper.prepare()

You are accessing something on the UI thread from inside doInBackground. And that's not allowed.

*edit: I've seen everything. To me, what looks mostly unusual are those lines:

updateWithNewLocation(location); // What does this do? Could you tell me?
locationManager.requestLocationUpdates(provider, 2000, 10,
        locationListener); // I don't think this is it

Try to move all those location update stuff into the onProgressUpdate. I'm blind here since I can't see your code, but I'm guessing it does something with the UI. Try this:

@Override
protected void onProgressUpdate(Location... locations) {
    super.onProgressUpdate(values);
    updateWithNewLocation(location);
}

But as I said, I'm not sure since I can't know what updateWithNewLocation does unless you post that code here.
