Can not perform this action after onSaveInstanceState in setNavigator

[xpathexception]

Activity's OnResume and OnPause looks exactly like this

@Override
protected void onResume(){
    super.onResume();
    MyApp.INSTANCE.getNavigatorHolder().setNavigator(navigator);
}

@Override
protected void onPause(){
    MyApp.INSTANCE.getNavigatorHolder().removeNavigator();
    super.onPause();
}

This exception is reported by remote device and I really don't know how reproduce it, so the only information I have is the following stack trace:

I have two different devices which was affected by this issue:

Philips V377 Android 5.1
UMI X2 Android 4.2.1

Hi! Please look at the Readme. We added the Attention about it. With support fragments you need to use onResumeFragments() insteed of onResume().
