Android开发中获取本机Mac地址和IP地址的方法

1、Android  获取本机Mac 地址方法：

  

    需要在AndroidManifest.xml文件中添加权限：   

"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 en = NetworkInterface
                    .getNetworkInterfaces(); en.hasMoreElements();) {
                NetworkInterface intf = en.nextElement();
                for (Enumeration 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;
    }
