[Aerogear-users] Android SDK - Token not renewed when unregistering/registering

[Summers Pittman]

Matthias,

https://github.com/aerogear/aerogear-android-push/pull/46

If would can, can you test this PR against your code and confirm the issue
is fixed for you?  If you don't want to build the project (and you probably
don't need to) I have attached the aar for the PR to this post.
