Cordova fails

Hello,
when adding your package, I get the following error on build:

```

It has something to do with phonegap-plugin-push. I got the same error when I only add that Cordova plugin to my project. I'm using Meteor 1.2

Reproduce the Android build with only phonegap-plugin-push added to a Meteor 1.2 project and inspect the reported dex merge failure. The issue is resolved when the build no longer reports multiple definitions of android/support/annotation/AnimRes.
