Android API-23:InetAddressUtils替换

Question

切换到Android棉花糖API,我使用org.apache.http.conn.util.InetAddressUtils了InetAddressUtils.isIPv4Address(ipAddress)一个代码,列出从设备的所有IP.

作为API-23更改的一部分,该InetAddressUtils课程现已消失.

我现在如何替换以下代码？

public static String ipAddress() {
    try {
        for (final Enumeration<NetworkInterface> enumerationNetworkInterface = NetworkInterface.getNetworkInterfaces(); enumerationNetworkInterface.hasMoreElements();) {
            final NetworkInterface networkInterface = enumerationNetworkInterface.nextElement();
            for (Enumeration<InetAddress> enumerationInetAddress = networkInterface.getInetAddresses(); enumerationInetAddress.hasMoreElements();) {
                final InetAddress inetAddress = enumerationInetAddress.nextElement();
                final String ipAddress = inetAddress.getHostAddress();
                if (! inetAddress.isLoopbackAddress() && InetAddressUtils.isIPv4Address(ipAddress)) {
                    return ipAddress;
                }
            }
        }
        return null;
    }
    catch (final Exception e) {
        LogHelper.wtf(null, e);
        return null;
    }
}

Answer 1

就像我从评论中解释一样,您可以使用此比较替换该函数:

inetAddress instanceof Inet4Address

所以你的代码将以:

if(!inetAddress.isLoopbackAddress() && inetAddress instanceof Inet4Address) {

Answer 2

将下面添加到您的 build.gradle(Module:app) 文件中，

android { useLibrary 'org.apache.http.legacy'}
