android4.0 擷取手機IP地址的問題

 擷取手機IP地址的代碼:

public static 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 e) {// TODO: handle exceptionUtils.log("WifiPreference IpAddress---error-" + e.toString());}return null; }

但是在4.0 下 會出現類似fe80::b607:f9ff:fee5:487e的IP地址, 這個是IPV6的地址,我們需要獲得是的IPV4的地址,所以要在上訴代碼中加一個判斷

InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())

完整代碼如下:

public static 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() && InetAddressUtils.isIPv4Address(inetAddress.getHostAddress())) {                                              return inetAddress.getHostAddress().toString();                      }                  }   }}catch (SocketException e) {// TODO: handle exceptionUtils.log("WifiPreference IpAddress---error-" + e.toString());}return null; }
