Android中出现java.net.BindException:bindfailed:EADDRINUSE问题解决办法

try{

DatagramSocket udpSocket = new DatagramSocket(DEFAULT_PORT );

} catch (Exception e)

{

e.printStackTrace();

}

//java.net.BindException: bind failed: EADDRINUSE (Address already in use)

if(udpSocket==null){
udpSocket = new DatagramSocket(null);
udpSocket.setReuseAddress(true);
udpSocket.bind(new InetSocketAddress(DEFAULT_PORT));
}
