Accessibility on android back arrow announce "null" item #11

Hi,

I have a issue with Accessibility on Android. I creat a ContentPageRenderer in Android to make the back arrow could announce anything what I expected. Following is my renderer code for back arrow accessibility:

    protected override void OnElementChanged(ElementChangedEventArgs<Page> e)
    {
        base.OnElementChanged(e);

        Activity context = (Activity)this.Context;
       // to find out the back arrow
        var toolbar = context.FindViewById<Toolbar>(Resource.Id.toolbar);

        if(toolbar!=null)
            //to set which string to announce.
            toolbar.NavigationContentDescription = "Go to previous page";
    }

but If my page inherit from "ContentPage" and "INavigationPopInterceptor" at the same time, the accessibility will announce "null", just like built-in ContentPage. Sorry, I'm not a native English speaker, hope you can understand what I say. If you have any question, I will reply you ASAP, thank you in advance for your effort.
