Google Play Lib Conflicts
Some unity plugins (like Heyzap, for example) require google play lib service to be imported into the project while with Android Native you have already included your own version of google play service lib. So, which one should I use in this case?
Our position is pretty simple here.
1) You can always find out play service lib version that was shipped with the plugin with the editor settings window:
2) Android Native always comes with the latest version of the play service lib.
So, in case you have few plugins in your project with the google play lib requirement, our recommendation - always use the latest available google play service lib version. You can download the latest version from Android SDK or just pick choose between few google play libs already imported in your project and pick the latest one.
In case play service lib version in your project is older than specified in the plugin's settings, it may cause issues as older version may not have the latest google play feature. But simple things as connection, friends, leaderboards and achievements will work anyway.
In case play service lib version in your project is newer than specified in the plugin settings, you will not have any issues at all.
