Config changes

Hi,

as discussed on the mailing list (topic "my experience with aerogear-android push") I needed some configuration changes in order to get everything running. Here are my changes. Since I used the "push" branch, I'm creating the PR on this branch, too, I hope this correct :)
If anything is wrong with this PR, let me now, it's my first contribution to an open source project (better late than never ;-) ), and I also didn't use PRs a lot until now.

Kind regards,

Marc
