I am working on a test app to test an ane I have built with Google Play Services included. I had things working fine, but recently I updated the version of the Google Play Services library I was using, and now when I built the project in Adobe Flash CC, it seems to be stripping out the Google Play Services classes from the apk. When I decompile the apk I can see they are missing. When I put back the old version of GPlay, I can see it doesn't strip them out.
This post mentions a tool within the AIR needs updating (dx.jar) and this post seems to have the same message. I did update that file but it did not fix the issue.
Thanks!
