getting exception “IllegalStateException: Can not perform this action after onSaveInstanceState”

Question

I have a Live Android application, and from market i have received following stack trace and i have no idea why its happening as its not happening in application code but it

Answer 1

This is fixed in Android 4.2 and also in the support library's source.[*]

For details of the cause (and work-arounds) refer to the the Google bug report: http://code.google.com/p/android/issues/detail?id=19917

If you're using the support library then you shouldn't have to worry about this bug (for long)[*]. However, if you're using the API directly (i.e. Not using the support library's FragmentManager) and targeting an API below Android 4.2 then you will need to try one of the work-arounds.

[*] At the time of writing the Android SDK Manager is still distributing an old version that exhibits this bug.

Edit I'm going to add some clarification here because I've obviously somehow confused whoever down-voted this answer.

There are several different (but related) circumstances that can cause this exception to be thrown. My answer above is referring to the specific instance discussed in the question i.e. a bug in Android which has subsequently been fixed. If you're getting this exception for another reason it's because you're adding/removing fragments when you shouldn't be (after fragment states have been saved). If you're in such a situation then perhaps "Nested Fragments - IllegalStateException “Can not perform this action after onSaveInstanceState”" can be of use to you.
