JAVA如何获取局域网内所有安卓设备的ip地址,MAC以及序列号?
1.得到局域网网段,可由自己机器的IP来确定 (也可以手动获取主机IP-CMD-ipconfig /all)
2.根据IP类型,一次遍历局域网内IP地址
JAVA类,编译之后直接运行便可以得到局域网内所有IP,具体怎样使用你自己编写相应代码调用便可
代码如下::
package bean;
import java.io.*;
import java.util.*;
public class Ip{
static public HashMap ping; //ping 后的结果集
public HashMap getPing(){ //用来得到ping后的结果集
return ping;
}
//当前线程的数量, 防止过多线程摧毁电脑
static int threadCount = 0;
public Ip() {
ping = new HashMap();
}
public void Ping(String ip) throws Exception{
//最多30个线程
while(threadCount30)
Thread.sleep(50);
threadCount +=1;
PingIp p = new PingIp(ip);
p.start();
}
public void PingAll() throws Exception{
//首先得到本机的IP,得到网段
InetAddress host = InetAddress.getLocalHost();
String hostAddress = host.getHostAddress();
int k=0;
k=hostAddress.lastIndexOf(".");
String ss = hostAddress.substring(0,k+1);
for(int i=1;i =255;i++){ //对所有局域网Ip
String iip=ss+i;
Ping(iip);
}
//等着所有Ping结束
while(threadCount0)
Thread.sleep(50);
}
public static void main(String[] args) throws Exception{
Ip ip= new Ip();
ip.PingAll();
java.util.Set entries = ping.entrySet();
Iterator iter=entries.iterator();
String k;
while(iter.hasNext()){
Map.Entry entry=(Map.Entry)iter.next();
String key=(String)entry.getKey();
String value=(String)entry.getValue();
if(value.equals("true"))
System.out.println(key+"--"+value);
}
}
class PingIp extends Thread{
public String ip; // IP
public PingIp(String ip){
this.ip=ip;
}
public void run(){
try{
Process p= Runtime.getRuntime().exec ("ping "+ip+ " -w 300 -n 1");
InputStreamReader ir = new InputStreamReader(p.getInputStream());
LineNumberReader input = new LineNumberReader (ir);
//读取结果行
for (int i=1 ; i 7; i++)
input.readLine();
String line= input.readLine();
if (line.length() 17 || line.substring(8,17).equals("timed out"))
ping.put(ip,"false");
else
ping.put(ip,"true");
//线程结束
threadCount -= 1;
}catch (IOException e){}
}
}
}
java如何对路由器实时获取连接到的手机的mac地址
package tmp;
import java.net.NetworkInterface;
import java.util.Enumeration;
public class MacUtil {
public static String getMacAddress() throws Exception {
String s="";
EnumerationNetworkInterface ni = NetworkInterface
.getNetworkInterfaces();
while (ni.hasMoreElements()) {
NetworkInterface netI = ni.nextElement();
byte[] bytes = netI.getHardwareAddress();
if (netI != null bytes != null bytes.length == 6) {
StringBuffer sb = new StringBuffer();
for (byte b : bytes) {
// 与11110000作按位与运算以便读取当前字节高4位
sb.append(Integer.toHexString((b 240) 4));
// 与00001111作按位与运算以便读取当前字节低4位
sb.append(Integer.toHexString(b 15));
sb.append("-");
}
sb.deleteCharAt(sb.length() - 1);
s+=sb.toString().toUpperCase()+"\n";
}
}
return s;
}
public static void main(String[] args) throws Exception {
System.out.println(MacUtil.getMacAddress());
}
}
如何使用Java代码获取Android和ios移动终端Mac地址
通过设备开通WiFi连接获取Mac地址是最可取的,代码如下:

/**
* 设备开通WiFi连接,通过wifiManager获取Mac地址
*
* @author 高焕杰
*/
public static String getMacFromWifi(Context context){
ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
State wifiState = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();
if(wifiState == NetworkInfo.State.CONNECTED){//判断当前是否使用wifi连接
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
if (!wifiManager.isWifiEnabled()) { //如果当前wifi不可用
wifiManager.setWifiEnabled(true);
}
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
return wifiInfo.getMacAddress();
}
return null;
}
除了上面这种方法,网上还给出了另外两种方法:
1、通过调用Linux的busybox命令获取Mac地址:

/**

*
* @author 高焕杰
*/
private static String getMacFromCallCmd(){
try {
String readLine = ;
Process process = Runtime.getRuntime().exec(busybox ifconfig);
BufferedReader bufferedReader = new BufferedReader (new InputStreamReader(process.getInputStream()));
while ((readLine = bufferedReader.readLine ()) != null) {//执行命令cmd,只取结果中含有HWaddr的这一行
if(readLine.contains(HWaddr)){
return readLine.substring(readLine.indexOf(HWaddr)+6, readLine.length()-1);
}
}
}catch(Exception e) { //如果因设备不支持busybox工具而发生异常。
e.printStackTrace();
}
return null;
}
注意:这种方法在Android Pad中可以准确获取到的Mac地址,但是在Android手机中无法准确获取到。
2、通过查询记录了MAC地址的文件(文件路径:“/proc/net/arp”)获取Mac地址:

/**

*/
private static String getMacFromFile(Context context){
String readLine =;
BufferedReader bufferedReader = null;
try {
bufferedReader = new BufferedReader(new FileReader(new File(/proc/net/arp)));
int rollIndex = 0;
while((readLine = bufferedReader.readLine())!=null){
if(rollIndex == 1){
break;
}
rollIndex = rollIndex + 1;
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (bufferedReader != null) {
try {
bufferedReader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
if(readLine !=null readLine.length()1){
String[] subReadLineArray = readLine.split( );
int rollIndex = 1;
for(int i = 0; i subReadLineArray.length; ++i){
if(!TextUtils.isEmpty(subReadLineArray[i])){
if(rollIndex == 4){
return subReadLineArray[i];
}
rollIndex = rollIndex + 1;
}
}
}
return null;
}
注意:无论在Android Pad中还是在Android手机中,这种方法都无法准确获取到Mac地址。
请问java如何获取手机mac地址?
以windows举例。
运行命令" cmd ipconfig /all"就会出现以下结果
Physical Address. . . . . . . . . : 20-CF-30-9A-60-EE
。
java就能过这样的命令来获取。以下是示例。
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class TestMac
{
public static void main(String[] args) {
System.out.println("Operation System=" + getOsName());
System.out.println("Mac Address=" + getMACAddress());
System.out.println("通过ip获取mac"+getMACAddress("192.168.1.101"));
}
public static String getOsName() {
String os = "";
os = System.getProperty("os.name");
return os;
}
public static String getMACAddress() {
String address = "";
String os = getOsName();
if (os.startsWith("Windows")) {
try {
String command = "cmd.exe /c ipconfig /all";
Process p = Runtime.getRuntime().exec(command);
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
if (line.indexOf("Physical Address") 0) {
int index = line.indexOf(":");
index += 2;
address = line.substring(index);
break;
}
}
br.close();
return address.trim();
} catch (IOException e) {
}
} else if (os.startsWith("Linux")) {
String command = "/bin/sh -c ifconfig -a";
Process p;
try {
p = Runtime.getRuntime().exec(command);
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = br.readLine()) != null) {
if (line.indexOf("HWaddr") 0) {
int index = line.indexOf("HWaddr") + "HWaddr".length();
address = line.substring(index);
break;
}
}
br.close();
} catch (IOException e) {
}
}
address = address.trim();
return address;
}
public static String getMACAddress(String ipAddress) {
String str = "", strMAC = "", macAddress = "";
try {
Process pp = Runtime.getRuntime().exec("nbtstat -a " + ipAddress);
InputStreamReader ir = new InputStreamReader(pp.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
for (int i = 1; i 100; i++) {
str = input.readLine();
if (str != null) {
if (str.indexOf("MAC Address") 1) {
strMAC = str.substring(str.indexOf("MAC Address") + 14,
str.length());
break;
}
}
}
} catch (IOException ex) {
return "Can't Get MAC Address!";
}
//
if (strMAC.length() 17) {
return "Error!";
}
macAddress = strMAC.substring(0, 2) + ":" + strMAC.substring(3, 5)
+ ":" + strMAC.substring(6, 8) + ":" + strMAC.substring(9, 11)
+ ":" + strMAC.substring(12, 14) + ":"
+ strMAC.substring(15, 17);
//
return macAddress;
}
}
剑天梦的回答原理和我这个一样,都是通过Process 执行命令。 我直接补充到答案里了。不过
我这边运行那个命令出来的结果很多,那么花的时间就长了。优点是能够获取别人的mac地址 。
