Xamarin provides necessary bindings for iOS and Android, and Countly SDKs for iOS and Android can be used with Xamarin.
This is how you can do it:
- Create binding projects in Xamarin for Android (and/or) iOS
- Use Xamarin IDE to import the Countly SDK (same for the Android project)
- Xamarin creates the binding definitions. Tweak the definition.
- Build and you now have a Xamarin SDK for iOS/Android to be used to send data to Countly.
Here are corresponding iOS and Android SDK guides:
Hope that helps!
