    I have added the following two lines to my .csproj file and now I don't get the JAVA0000 anymore. https://github.com/xamarin/GooglePlayServicesComponents/issues/852

    <PackageReference Include="Xamarin.AndroidX.Collection.Jvm" Version="1.4.0.1" /> <PackageReference Include="Xamarin.AndroidX.Collection.Ktx" Version="1.4.0.1" />

    In addition, I found out that the NuGet package Plugin.InAppBilling (7.1.2-beta) created the AMM0000 error. I removed this package and installed the NuGet package Plugin.InAppBilling (7.1.0) and now it works.
