I found this question whith a similar error: "https://stackoverflow.com/questions/57495384/crash-on-calligraphy-library-by-chris-jenx-for-android-q".
The anwser for that was migrate to Calligraphy 3, can i do this in Xamarin.Android? How? Could be something else? What?
回答1:
I suggest you to take a look at this guide
I faced the same problem on a legacy Xamarin.Android project and I solved it removing Calligraphy. This is not a big problem since you must support and target API 28 (29 from November 2th). The problem was solved in Calligraphy 3+ but that version of library is currently not up to date in available Xamarin Nuget packages (they are still base on calligraphy 2).
