PopToRootAsync in OnResume

Hello,

i would like to navigate to my root page when the app resumes.

On iOS i can use this in my App.cs:

protected override async void OnResume()
{
    await App.Current.MainPage.Navigation.PopToRootAsync ();
}

On Android (with AppCompat) this results in an error message:

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

What can i do to make this work?
