本文提供了一种在Android环境中获取设备IP地址和MAC地址的方法，包括3/4G网络、Wi-Fi网络和有限网络的不同情况。通过使用ConnectivityManager、WifiManager等API，实现了对不同网络环境下IP地址的获取，并通过InetAddress进一步获取了MAC地址。

public static String getIpAddress(Context context){
    NetworkInfo info = ((ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();
    if (info != null && info.isConnected()) {
        // 3/4g网络
        if (info.getType() == ConnectivityManager.TYPE_MOBILE) {
            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() && inetAddress instanceof Inet4Address) {
                            return inetAddress.getHostAddress();
                        }
                    }
                }
            } catch (SocketException e) {
                e.printStackTrace();
            }

        } else if (info.getType() == ConnectivityManager.TYPE_WIFI) {
            //  wifi网络
            WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();
            String ipAddress = intIP2StringIP(wifiInfo.getIpAddress());
            return ipAddress;
        }  else if (info.getType() == ConnectivityManager.TYPE_ETHERNET){
            // 有限网络
            return getLocalIp();
        }
    }
    return null;
}

private static String intIP2StringIP(int ip) {
    return (ip & 0xFF) + "." +
            ((ip >> 8) & 0xFF) + "." +
            ((ip >> 16) & 0xFF) + "." +
            (ip >> 24 & 0xFF);
}


// 获取有限网IP
private static String getLocalIp() {
    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()
                        && inetAddress instanceof Inet4Address) {
                    return inetAddress.getHostAddress();
                }
            }
        }
    } catch (SocketException ex) {

    }
    return "0.0.0.0";

}

public static String getMacAddressFromIp(Context context) {
    String mac_s= "";
    StringBuilder buf = new StringBuilder();
    try {
        byte[] mac;
        NetworkInterface ne=NetworkInterface.getByInetAddress(InetAddress.getByName(getIpAddress(context)));
        mac = ne.getHardwareAddress();
        for (byte b : mac) {
            buf.append(String.format("%02X:", b));
        }
        if (buf.length() > 0) {
            buf.deleteCharAt(buf.length() - 1);
        }
        mac_s = buf.toString();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return mac_s;
