Java/Android: DatagramChannel is already set non-blocking, receive() still blocks
<p>I set the <code>datagramchannel</code> non-blocking by instance method <code>configureBlocking(false)</code>,
But when I use instance method <code>receive(buffer)</code>, it still hangs there for incoming packet. Anyone could tell me what's going on?</p>

<p>Thanks.</p>
