Recent I’ve this bug on my project.
This bug comes when app awake from sleep.
I’ve spent a lot of time to fix it. And finally I got the solution.
My project is Activity with Fragments.
The error text is:
java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

To fix it you need save instance of your Fragments. To do this you need just override onSaveInstanceState method for your Fragment.
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putString(BundleKeys.MESSAGE, message);
}
Also you need restore fragment state in onCreateView of onActivityCreated methods
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (savedInstanceState != null) {
if (!savedInstanceState.isEmpty()) {
Loger.i(TAG, "!savedInstanceState.isEmpty()");
if (message == null) {
message = new Gson().fromJson(savedInstanceState.getString(BundleKeys.MESSAGE), Message.class);
}
}
}
}
Hope it help you.
