Hello, i test your library on Huawei P20 Lite with android 8.0, but i get this errors:

System.NullReferenceException: Object reference not set to an instance of an object.

My code is: public static async Task isFingerUserAsync() { var availability = await CrossFingerprint.Current.GetAvailabilityAsync(); Console.WriteLine(availability); var result = await CrossFingerprint.Current.AuthenticateAsync("Prove you have fingers!"); if (result.Authenticated) { return true; } return false; }

On availability i get 12-09 20:01:42.970 D/Mono (16175): Assembly Ref addref Plugin.Fingerprint.Abstractions[0x7dfc636800] -> System.Threading.Tasks[0x7e1f8d6980]: 3 12-09 20:01:42.973 D/Mono (16175): Assembly Ref addref Plugin.Fingerprint[0x7dfc636780] -> Plugin.Fingerprint.Android.Samsung[0x7dfc636a00]: 2 12-09 20:01:42.981 D/SM_SDK (16175): Could not find ContextProvider 12-09 20:01:42.981 D/SM_SDK (16175): versionCode: -1

Hi @xperiafan13-rom,

I'm the friendly issue checker. It seems like (100.00 %) you haven't used our issue template :cry: I think it is very frustrating for the repository owners, if you ignore them.

If you think it's fine to make an exception, just ignore this message. But if you think it was a mistake to delete the template, please close the issue and create a new one.

Thanks!
