Android Progressbar not updating

Question

Answer 1

You are updating progress bar inisde a thread's run method. you cannot update ui from a thread. You need to update ui on the ui thread. Use runOnUiThread. runOnUiThread is a method of activity class.

Or Use Asynctask.

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

In asynctask doInBackground you can call publishProgress(Progress...) to publish one or more units of progress. These values are published on the UI thread, in the onProgressUpdate(Progress...) step.
