Suddenly, I started getting this error from the moment the support library was updated, which leads to the application crashing at startup, even if everything builds perfectly. I tried using lower versions of packages, which gave me the same error. I tried to completely reinstall the Xamarin and Android SDK, and finally create a new project that uses AppCompat but does not succeed.
Android v22.2 Support Library
Packages:
- Xamarin.Android.Support.v7.AppCompat v22.2
- Xamarin.Android.Support.v7.MediaRouter v22.2
- Xamarin.Android.Support.v4 v22.2
- Xamarin.Android.Support.v13 v22.2
- Xamarin.GooglePlayServices v22.2.0.2
