I get this error on crashlytics panel:

I override manifest for library to use it with api level 10 and I already test it on android 2.3.3 and it was working ok! but now I see this crash on crashlytics. Hi I can fix this for my version? is crash related to api 10? because the method is for support v4 library so I can't understand why this occurred.
yes the method isChangingConfigurations() has been introduced with API 11:
https://developer.android.com/reference/android/app/Activity.html#isChangingConfigurations()
as part of theandroid.app.Activity plattform class (and not as part android.support.v4.app.FragmentActivity, but FragmentActivity extends Activity).
Hence, this won't work on API < 11.
You could implement isChangingConfigurations() in your Activity and either call
super.isChangingConfigurations() if API >=11 or implement your own thing if (API < 11). You may want to take a look at Activities source code, but I'm not sure how this could be back ported. https://github.com/android/platform_frameworks_base/blob/master/core/java/android/app/Activity.java#L5152
You could try to just return false if API < 11 . That would mean that the View's state (and Presenter) will not survive screen orientation changes. DISCLAIMER: That might also cause some other unwanted side effects I'm not aware of right now and could break with any future release of Mosby or support library.
