"java.lang.UnsupportedOperationException" using Net.WebSocket on android

I'm just trying to connect to my websocket server :

ws = net().createWebSocket("ws://192.168.0.3:8000/sample", this);

It works fine when I test it with mvn test -Pjava

But when I load it with my Google Nexus S (under Icecream sandwich), I get :

Solution

  • WebSockets are (as of March 2013), not supported in the Android backend. They're only supported in the Java and HTML backends.

    I'll update the platform status page.
