Google Play Services Error - Bug report Incomprehensible

Question

I have released an alpha version of my app with Google Play services. However, I have encountered this error when I tested the app on a phone with Google Play services. I hadn't got this error during compilation or running the app on a phone with an out of date Google Play Service. I Googled this error and in stack overflow but it didn't give me much answer. If anyone have any idea, please help.

By the way, I didn't enable pro-guard, so that isn't a problem

Here is the bug report:

java.lang.IllegalStateException: A fatal developer error has occurred.

By the way, I use LibGdx, and I used google play services for leader boards, a achievements. I have followed this tutorial but it didn't help me much. Thanks in advance

Answer 1

I forgot to post the answer after I solved the problem several months ago!

The problem was an extra space in the ID of the leaderboard.

Supposed that my leaderboard ID is "as129sadf92349dsfaj".

I wrote "as129sadf92349dsfaj ".

So google play services gave me this error.
