What is the best practice for dealing with Game Circle in Non-Kindle Fire devices? Specifically: should we remove any buttons that would like to achievements / leaderboard? (or) should we simply pop up a message to the user, telling them their device is not supported? Any other suggestions are also welcome.
As per our FAQ, we suggest you can either make one binary that handles both environments (Kindle and general Android), or you can make a separate binary for each environment. Its developer choice to either gracefully degrade your app for GameCircle on non-Amazon devices or have separted binaries. For more information on GameCircle pls refer our GameCircle FAQ at
