Android获取本机Mac地址及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：

<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 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;
	}
