Xamarin Android and iOS bindings for the Twilio Conversation SDKs.
General Documentation: https://www.twilio.com/docs/conversations/fundamentals
Android SDK API Reference: https://media.twiliocdn.com/sdk/android/conversations/releases/4.0.2/docs/
iOS SDK API Reference: https://media.twiliocdn.com/sdk/ios/conversations/releases/2.2.7/docs/
In the Twilio Conversations SDK for Android, some types are defined as interfaces, so the Xamarin binding tools generated a corresponding C# interface, prefixing the class name with an "I" to follow C# naming conventions. One example is the ConversationsClient interface, which is exposed in C# as IConversationsClient.
So, to create a conversations client (for Android), you must call either IConversationsClient.Create or IConversationsClient.CreateAsync, like this:
string token = "<twilio access token>";
var properties = IConversationsClient.ClientProperties.NewBuilder().CreateProperties(); // You can specify some options here; please refer to the API reference for more information.
var conversationsClient = await IConversationsClient.CreateAsync(Application.Context, token, properties);
Sometimes, when building your Android project after you have included the Twilio.Conversations.Xamarin package, you will see some warnings in the build output window:
2> Warning in obj\Debug\120\lp\7\jl\__reference__kotlinx-coroutines-core-jvm-1.5.0-native-mt.jar:kotlinx/coroutines/debug/AgentPremain.class at Lkotlinx/coroutines/debug/AgentPremain;installSignalHandler()V:

These warnings can be safely ignored; the SDK will still work fine regardless. I haven't figured out a way to hide them yet, but if you do know of a way, you can create a pull request. Thank you!
