I’m no longer maintaining the airbrake notifier since I’ve moved to using Bugsnag. I recommend you start using Bugsnag to track errors in your Android apps too.
Bugsnag is better suited to tracking exceptions on mobile applications and has a bunch more awesome features such as user-centric error counts, smart grouping, chat notification (HipChat, Campfire, etc) automatic ticket creation (GitHub Issues, Pivotal Tracker, Lighthouse, Codebase, etc) and more.
You can still find the deprecated airbrake notifer on github.
