android獲得mac和ip

 

1、Android  擷取本機Mac 地址方法：

  

    需要在AndroidManifest.xml檔案中添加許可權：    

 <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();}

 

2、Android 擷取本機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;}
