Failure saving state - target not in fragment manager (setTargetFragment)

Question

I\'ve got a monkey crash whereby

java.lang.IllegalStateException: Failure saving state: FragmentB has target not in fragment manager: FragmentA
at android.s         


        

Answer 1

I had this issue when showing a DialogFrament from another Fragment and using setTargetFragment on the DialogFragment. The issue was solved using getChildFragmentManager() when displaying the DialogFragment.

1. ActivityA added FragmentA
2. FragmentA added DialogFragmentB using ActivityA's FragmentManager.
3. Called dialogFragmentB.setTargetFragment(fragmentA)
4. Removed FragmentA and added new instance of FragmentA
5. The FragmentManager associated with ActivityA still contained DialogFragmentB which had the first instance of FragmentA as target fragment.

This caused "Failure saving state - target not in fragment manager" exception to be called.

There were few changes regarding onSaveInstance() lifecycle order between Pre-HoneyComb and post-Honeycomb libraries. Please refer this article for more info:
