Android udpserver不断接收数据信息问题
通过udpserver循环接收客户端发来的数据，将所有的数据显示在界面我这边就通过while循环在线程中接收数据，然后通过handler将数据显示在主界面上！可是为什么有时候会卡死！
public class UDPServer implements Runnable {
private byte[] msg = new byte[1024];
private boolean life = true;
private DatagramSocket dSocket = null;
public UDPServer() {
try {
dSocket = new DatagramSocket(17009);
} catch (SocketException e) {
e.printStackTrace();
}
}
/**
* @return the life
*/
public boolean isServer() {
return life;
}
/**
* @param lifes the life to set
*/
public void setServer(boolean lifes) {
this.life = lifes;
LogUtil.e("dSocket.isClosed()show==");
if (life == false && dSocket != null) {
if (!dSocket.isClosed()) {
dSocket.close();
}
dSocket.disconnect();
// dSocket = null;
}
}
@Override
public void run() {
DatagramPacket dPacket = new DatagramPacket(msg, msg.length);
while (life) {
try {
Thread.sleep(5);
if (dSocket != null) {
dSocket.receive(dPacket);
String datas = ByteUtil.byte2HexStr(dPacket.getData(), dPacket.getLength());
//将收到的消息发给主界面
if (dPacket.getAddress() != null) {
Message message = new Message();
message.obj = dPacket.getAddress() + "--" + datas;
message.what = 2;
myHandler.sendMessage(message);
}
} else {
life = false;
}
} catch (IOException e) {
life = false;
if (dSocket != null) {
if (!dSocket.isClosed()) {
dSocket.close();
}
dSocket.disconnect();
}
} catch (InterruptedException e) {
life = false;
if (dSocket != null) {
if (!dSocket.isClosed()) {
dSocket.close();
}
dSocket.disconnect();
}
}
}
}
