Hi folks!
I’ve burned several hours to find the reason of the problem.
ClassNotFoundException: com.gameanalytics.sdk.GameAnalytics
Finally I solved it and posting here to prevent time loss for you 
When building for Android, Proguard minification process removes Game Analytics java libraries. Keep away from proguard when using Game Analytics for Android. Set Minify to None in Player Settings.
Hope it helps.
very helpful! thanks a lot!
Thanks!
I was trying to get rid off google warnings when was uploading to Google Play.
The warning suggests you to minify your files. I did it and then GameAnalytics stoped working.
I think you just need to take the proguard rules from here: Platform Overview - GameAnalytics Documentation and add them to the proguard file
Man, You saved me! Thanks a lot!!!
