For example, change your code to: Intent myIntent = new Intent(getApplicationContext(), AlarmAlertBroadcastReciever.class); Bundle bundle = new … Read more

If you implement your tabs as views, rather than individual activities, this would be far simpler, run faster, take up less memory, and be a better solution IMHO. That being said, in the Tab A Activity, call getParent() to get at the TabActivity. Then, you can use the methods pointed out by disretrospect.
