Android擷取手機ip程式碼

執行個體

代碼如下

複製代碼

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("ifo", ex.toString()); } return ""; } public String getLocalMacAddress(Context context) { WifiManager wifi = (WifiManager) context .getSystemService(Context.WIFI_SERVICE); WifiInfo info = wifi.getConnectionInfo(); return info.getMacAddress(); }

安卓4.0系統的手機，按上面的方法預設會先擷取到ipv6的地址，有時候我們只想要ipv4的地址
