android获得mac和ip .

 

1、Android  获取本机Mac 地址方法：

  

    需要在AndroidManifest.xml文件中添加权限：    

<span style="font-family:Arial;BACKGROUND-COLOR: #ffffff"> </span><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<span style="font-family:Arial;BACKGROUND-COLOR: #ffffff"> </span><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

 

public String getLocalMacAddress() {
        WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        WifiInfo info = wifi.getConnectionInfo();
        return info.getMacAddress();
    }

public String getLocalMacAddress() { WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); WifiInfo info = wifi.getConnectionInfo(); return info.getMacAddress(); }

 

2、Android 获取本机IP地址方法： 

  

public String getLocalIpAddress() {
    try {
        for (Enumeration<NetworkInterface> en = NetworkInterface
                .getNetworkInterfaces(); en.hasMoreElements();) {
            NetworkInterface intf = en.nextElement();
            for (Enumeration<InetAddress> enumIpAddr = intf
                    .getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = enumIpAddr.nextElement();
                if (!inetAddress.isLoopbackAddress()) {
                    return inetAddress.getHostAddress().toString();
                }
            }
        }
    } catch (SocketException ex) {
        Log.e("WifiPreference IpAddress", ex.toString());
    }
    return null;
}
