What

Investigate possibility to use bindings to existing Android/iOS SDKs/modules to use them in Xamarin SDK.

Why

It's possible to remove need to create all modules again directly in C#, but we can use modules from existing SDKs for Android .

How

From Wei's investigation:

ios: https://docs.microsoft.com/en-us/xamarin/ios/platform/binding-objective-c/walkthrough?tabs=vsmac
android: https://docs.microsoft.com/en-us/xamarin/android/platform/binding-java-library/

Swift is not supported by Xamarin itself, but it can be done as described in this post: https://medium.com/@Flash3001/binding-swift-libraries-xamarin-ios-ff32adbc7c76.
