Same problem here.
For me, everything is ok if I tap the back button at the bottom, but if I tap the back button on the ActionBar, the application crashes with the same exception you pasted.

@huanght1997 you are totally right. I just used the OS back button at the bottom and it saved with no problem. Thanks for the hint
