alert dialog inside asynctask in android

Question

I need to show the Alertdialog inside Asynctaskin android , but it won`t show in throws exception.

05-13 14:59:35.522: WARN/System.err(1179): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()

Thanks.

Answer 1

It isn't possible to manipulate the UI from the background thread. Use handler or the onPre/Post methods of the AsyncTask for that.

Answer 2

Show the dialog in onPostExecute() method rather than doInBackground.

Hope that helps

Answer 3

I think this might be your problem -- you can't show a dialog from inside doInBackground.
