I'm doing a game for Android. And I want to add google play leaderboards (and achievements). I've already tried to do this with Google Play plugin, but the build fails with Crosswalk. If I build with Android (no crosswalk), the build is successfull, but when user tries to sign in, he gets an error. [attachment=0:3ro5ok5g][/attachment:3ro5ok5g] If I build with Cocoon JS (Ludei), I can't upload it to Google Play, because one file is Debug, another one is unsigned.
So, the question is: How do I add Google Play leaderboards and export to Android?
