@tunjid I’m getting this error. What I’m trying is after launching MainActivity hitting the web API and launching fragment.

@tunjid I just found this: https://stackoverflow.com/a/10261449

I do have a onSaveInstanceState which add something in the outState after calling super. As I understand the accepted answer on the SO thread, the exception is happening because MultiStackNavigator is calling fragmentManager.commit instead of commitAllowingStateLoss.

We’ll try to fix our onSaveInstanceState as I don’t think changing from commit to commitAllowingStateLoss on your side is a proper solution!
