I recently received the following alert for my game in the Google Play Developer Console:
Detected incorrect implementation
Your game has incorrectly implemented the following Play Games services: Achievements.
It provides a link to a help page but the page only provides the following information:
Detected incorrect implementation
This game has implemented invitations but doesn't allow users to join a match from an invitation. This approach is discouraged because it could result in a poor user experience.
This does not help me because it mentions invitations (which my app does not use) instead of achievements.
I find it strange that I am getting the error now as I published the last update in May. I am also able to earn achievements when using the app myself, so the fact that I get this message bugs me.
Can you answer these questions:
Are these alerts ever erroneous? Is it possible my app is fine after all, or is there definitely something I did wrong?
If there is something wrong with my app, how do I go about fixing this? What are common sources of error that cause this message?
Is this message supposed to be a friendly reminder that I am doing something wrong or is it a warning that they will remove my app/terminate my account if I don't do something about it?
Thanks for the help.
Google had updated the information about the "Detected incorrect implementation".Please check the your "a help page".
Achievements: This game has created achievements in the Developer Console, but never calls the SDK's unlock methods. This approach is discouraged because it could result in a poor user experience.
I also encountered this warning and check the app really do not follow the checklist of google play services about achievements.Please re-check your app whether it follows the Required rows in the checklist.
I have already uploaded my modified app to google play.When the warning disappears, I will share the information with you.
The most common cause of this alert is when you call unlock or increment and pass an invalid id as per the games alert descriptions. Double check that the ids listed in the developer console match the ids listed in your game - preferably, use the 'Get resources' option in the Developer Console to get an XML file that you can be sure matches Google Play Games exactly.
I am also getting these messages, even for apps that dont have any integration with GPGS at all (No leaderboards, achievements ... they dont even include the api). Perhaps it's an issue with some kind of automated checking rollout.
