Unity3D Google Play Games: NoSuchMethodError when calling Authenticate

I am using Google Play Services Plugin for Unity3D from the following source https://github.com/playgameservices/play-games-plugin-for-unity

When I try to show my Leaderboards or Achievements I get this message:

It seems that the authenticate always returns false.

Right now the user is only able to log in to google play.

Solution

  • I ran into the same problem today. Apparently there was an update committed to the GitHub repository on the 13th (see https://github.com/playgameservices/play-games-plugin-for-unity/commit/eb70764bf8795de051520b3262745ef35c204c17#diff-bedb7e4c95811a7313c6e4ba5f18875f ) that appears to fix the problem. I merged all the changes from head and my app ran OK.
