IllegalStateException

Question

hi. I a developing an android two-player game. In method ondestroy I disconnect users. when I reload the app in emulator IllegalStateException happens and my code in ondestroy is not called and so when I see the lobby the previous user is shown to be online(because ondestroy wasn't called and as a result the user is considered online). how can I handle this so if any exception happens I can disconnect users? what is this IllegalStateException? here is the stacktrace:

Hi,

Are you using threads? If so please use runOnUIThread method to handle threads.

You might be using Connection resiliency. When connection resiliency is used, server retains the user for recover allowance time if disconnect is not called. But server will remove it after recovery allowance time is over.

Thanks
