Comment was:

in collapse mode, i swipe some items and hit the home button before the end of the undo bar

Unfortunately I wasn't able to reproduce that. So if anyone else had that behavior I would be very glad, if you let me know and help me reproduce it.

(I have an idea what it is, but to investigate it and see if possible solutions work, I would need to reproduce it.)

I think i was able to reproduce it with my set up. I have a Popupwindow that contains a https://github.com/chrisbanes/Android-PullToRefresh. I used SwipeToDismissUndoList for the list and when the SwipeToDismissUndoList executes the .showAtPosition for the mUndoPopup i get the

android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@42238078 is not valid; is your activity running?

Thanks for this information. I guess this will help me reproducing it, and hopefully fixing it.
