The stack trace when "reactor.execute(eventDispatch)":

The nio underlyings on Android is:
org.apache.harmony.nio.internal.SelectorImpl
org.apache.harmony.nio.internal.SocketChannelImpl

Fllowing James's instruction, i tried editing (DefaultConnectingIOReactor.java:97) by changing
key = socketChannel.register(this.selector, 0);
to
key = socketChannel.register(this.selector, SelectionKey.OP_CONNECT);
but this problem persists.

After seaching web i fount this maybe can provide some help.
