Android如何从设备中查找动态IP？

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Build;
import android.util.Log;

public class NetworkUtil {
    public static String getIPAddress(Context context) {
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
        if (networkInfo != null && networkInfo.isConnected()) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                return networkInfo.getInterfaceName();
            } else {
                return networkInfo.getExtraInfo();
            }
        }
        return null;
    }
}
