SDK version value should reflect the version of the SDK, not the version of the app
Right now, it's taking whatever version the app is taking (see below link). It should instead take the version of the Chatkit SDK from the file releases.

Actually, it might refer to the version here: https://github.com/pusher/chatkit-android/blob/master/chatkit-android/build.gradle#L19
It's possible to move the version assignment into an external variable and increment it there for both bintray version as well as for the buildConfig version.
We're looking at updating this process for v2 - watch this space 🙂
