My app is setup so that my root activity is Menu Buttons, which extends BT_fragment, so adding the code snippet there won't work.

You should be able to put it inside the main activity. This is due to "Late-Binding" of overridden methods. The compiler does not compile these methods until it finds the most recent one (in the lowest extended class) Search through the project for where the back button is initialized (possibly in BT_activity?) and try to put the code there. Does this help? Jake Comments Does this perform the same function as the home button? You should be able to put it inside the main activity. This is due to "Late-Binding" of overridden methods.

I only want it to come up on my Menu Buttons root activity.
