I add a bunch of FragmentTransactions to the back stack in one Tab, and I want to clear them ALL from the back stack when the user selects a different Tab. I can't find a method to clear stuff off the back stack, only methods to pop them off, and these don't even return the Fragment to you so you can close them. Any ideas?

Explanation: MainFragment -> Fragment A -> Fragment B (this is added to backstack) -> Fragment C -> MainFragment (clear backstack ).
Use finishAffinity(); in task C when starting task A to clear backstack activities. Show activity on this post. Use finishAffinity() to clear all backstack with existing one.
To remove a fragment from the host, call remove() , passing in a fragment instance that was retrieved from the fragment manager through findFragmentById() or findFragmentByTag() . If the fragment's view was previously added to a container, the view is removed from the container at this point.
FragmentManager is the class responsible for performing actions on your app's fragments, such as adding, removing, or replacing them, and adding them to the back stack.
If you add many Fragments to the backstack and want to remove them all you can do this: popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE)

Just remove them from the backstack using the popBackStack() methods.
Each fragment you pop is exactly the same as if the user had pressed the BACK button, and you don't do any special cleanup when the BACK button is pressed, right?
