I'm guessing here a little bit, but is this what you want?: The user is in ActivityA. THe user clicks on a button or does something that requires a background Thread to do so processing. When the Thread is done (successfully), the thread needs to spawn/start ActivityB
If so, use an AsyncTask. Subclass it into your own (static) subclass. Create an instance of this class. When the task needs to run, instantiate it and call 'execute' on it. This will cause its doInBackground method to run in a background thread. When this method return, the onPostExecute is called. Use this to start ActivityB. In the mean time, design your subclass to add a method that allows ActivityA to register itself (upon instantation/execute) and to deregister itself (e.g. when ActiivtA's onDestroy is called). If ActivityA is deregistered, you can code your subclass' doInBackground and/or onPostExecute method to stop or do nothing.
