Android Chat SDK - Identifying your users - Error handling missing

Feature Request Summary: 

There's a difference in SDK between iOS and Android, where Android could benefit from the information provided by its counterpart.

This is about Error Handling while authenticating users using the Android Chat SDK.

As your documentation and my exploration of the Android SDK, there's no way to identify why an authentication would fail in Android, whereas in iOS it's possible.

This will mainly be used for logging and reporting, so using the console logger using the following isn't an option.

Logger.setLoggable(true);

Description/Use Cases: 

It would be great to have platform parity between both SDKs to be able to report any errors, and in general, having platform parity for each feature/capability would be awesome! 

Business impact of limitation or missing feature:

Can't do reporting or track that the feature is working as expected which limits our visibility of the success of the rollout.

Also as it's available on iOS, it's making Android look bad.
