android thread / udp socket sample

IT知识android

黄沙百战穿金甲，不破楼兰终不还。这篇文章主要讲述android thread / udp socket sample相关的知识，希望能为你提供帮助。
class EventReadThread extends Thread {
boolean socketCreated = false;
DatagramSocket socket;
InetAddress serverAddress;
byte dataIn[] = new byte[1024];
private void Delay(int ms) {
try {
Thread:
sleep(ms);
} catch (Exception e) {
e.printStackTrace();
}
}
public void run() {
while (mThreadQuitFlag == 0) {
Delay(2000);
【android thread / udp socket sample】
if (socketCreated == false) {

String str = "gmx ls";
byte data[] = str.getBytes();
DatagramPacket packet = new DatagramPacket(data, data.length, serverAddress, 4568);
socket.send(packet);

} catch (Exception e) {
e.printStackTrace();
}
System.out.println("Read data from udp socket");
