Java – Google play game service invitation lost

I'm using the new Google play game service to develop my game on Android. Now I'm trying to add an invitation system. I have 3 Google accounts to try out invitations for 2 Android devices and 1 Android simulator

My problem is that you don't always receive invitations when you send them. Sometimes it works quickly and perfectly, sometimes it doesn't work. Just cancel the invitation and try again to change the results

I did three tests here just to make it clearer:

Test 1: the simulator is the invitee, nexus 4 did not receive it, and Optimus one received it

Test 2: Nexus 4 is the invitee, the emulator receives it, and Optimus one receives it

Test 3: Optimus one is the invitee, the emulator receives it, but nexus 4 does not

From these results, we can see that my nexus 4 has not received any invitation, but it has worked several times before these tests

In addition, sometimes I receive an invitation notice (on the status bar), but most of the time I don't receive it

Has anyone experienced the same abnormalities as me?

resolvent:

This may be related to the account you are logged in to. I found that I can send invitations from my development account to my test account, but not vice versa
