Xamarin Play Integrity API

Question

Xamarin Play Integrity API

Prabakaran Ramasamy 21

Is it planned to make Google's Play Integrity library available to Xamarin? I see a Xamarin nuget for SafetyNet, but it will be replaced by the Play Integrity API soon. I'll submit a feature request if its not in the plan.

Hello,

Base on my researching, there are no such NuGet packages or samples for Xamarin Play Integrity API. You could download the SDK from https://developer.android.google.cn/google/play/integrity/setup and try binding library, refer to https://learn.microsoft.com/en-us/xamarin/android/platform/binding-java-library/binding-an-aar

In addition, there is a feature request at https://github.com/xamarin/GooglePlayServicesComponents/issues/613, you could follow the progress.

Best Regards,

I made the Xamarin.Android binding. However, the following run time exception prevents me from proceeding. Do you have any suggestions for resolving this run-time exception?

Hi @PrabakaranRamasamy-6357, You could try to look at the di9agnostic build output for the binding project, searching for the missing type/method/etc. And see if the warning indicates why the type/method/etc. was not bound. Usually some reference type can't be found in the binding project, perhaps due to the referenced type having been obfuscated or perhaps a referenced type was private in the Java library, in which case transformations can make it public (or unobfuscated). Refer to https://gist.github.com/JonDouglas/dda6d8ace7d071b0e8cb
I notice that there are some updates at https://github.com/xamarin/GooglePlayServicesComponents/issues/613, you could follow the progress.
