Hi, I have looked into the code for several days. But I didn't find the root cause. Because even if I only call "new Connect", the problem will occur. So this should be related to Connect.java or ConnectAuthDefault.java. Would you take a quick at the issue and give some prompt? Then I can try to fix this. Thanks! B.R.

But if I run the garbage collection for the last problem, It will crash. I guess this problem is caused by ConnectAuth callback. When garbage collection is executed, the callback memory is moved. Okay, maybe some memory need to be pinned in some ways, I take patches !
