I'm a newbie with kryonet. I want to use kryonet in my libgdx game. When Server and Client run on desktop, they run well. But when server on desktop and client on Android, they got errors like this:

Anyone can help me? I'm sorry to bother.

It's mybe because of the JDK version. I install the Client and Server both on Android, they run well.
