I think the problem is that you should be using a service instead of a background thread as you will be able to control it better.The thread will probably become disconnected from the UI when you resume the activity.
With a service you should be able to pause/stop it when the user clicks back and then resume it when they reenter the UI. http://code.google.com/android/intro/lifecycle.html On Tue, Dec 30, 2008 at 8:54 AM, Dan <danscott0...@gmail.com> wrote: > > Hi All, > > I have a basic application running under the 1.0 SDK of Android.
