问题
It's new and it's sad. Since last Friday, it appears that Google have decided to limit the numbers of queries to the Leaderboard via loadCurrentPlayerLeaderboardScore.
I have a game that requests the access to 4 Leaderboards simultaneously, and since Friday, that's what I am receiving:
11-30 10:12:51.557 12993-12993/? I/LEADERBOARD: Request n0 : STATUS_OK
11-30 10:12:51.597 12993-12993/? I/LEADERBOARD: Request n1 : STATUS_OK
11-30 10:12:51.767 12993-12993/? I/LEADERBOARD: Request n2 : STATUS_OK
11-30 10:12:51.898 12993-12993/? I/LEADERBOARD: Request n3 : STATUS_NETWORK_ERROR_NO_DATA
If I invert the requests order:
11-30 10:30:31.431 12993-12993/? I/LEADERBOARD: Request n2 : STATUS_OK
11-30 10:30:31.642 12993-12993/? I/LEADERBOARD: Request n3 : STATUS_OK
11-30 10:30:31.832 12993-12993/? I/LEADERBOARD: Request n0 : STATUS_OK
11-30 10:30:31.952 12993-12993/? I/LEADERBOARD: Request n1 : STATUS_NETWORK_ERROR_NO_DATA
And finally, if I double the requests:
11-30 10:38:53.521 12993-12993/? I/LEADERBOARD: Request n0 : STATUS_OK
11-30 10:38:53.691 12993-12993/? I/LEADERBOARD: Request n1 : STATUS_OK
11-30 10:38:53.892 12993-12993/? I/LEADERBOARD: Request n2 : STATUS_OK
11-30 10:38:54.022 12993-12993/? I/LEADERBOARD: Request n3 : STATUS_NETWORK_ERROR_NO_DATA
11-30 10:38:55.944 12993-12993/? I/LEADERBOARD: Request n0 : STATUS_NETWORK_ERROR_NO_DATA
11-30 10:38:55.994 12993-12993/? I/LEADERBOARD: Request n1 : STATUS_NETWORK_ERROR_NO_DATA
11-30 10:38:56.084 12993-12993/? I/LEADERBOARD: Request n2 : STATUS_NETWORK_ERROR_NO_DATA
11-30 10:38:56.234 12993-12993/? I/LEADERBOARD: Request n3 : STATUS_NETWORK_ERROR_NO_DATA
Like you can see, only 3 requests are now authorized by Google. The official documentation mentions nothing about that. Any idea how to circumvent this?
Edit : After a couple of tests, I discovered that the limit is about of 3 requests max per +-20 sec.
