Solution for Android SDK Manage failure to update SDK

The simplest thing to do is to modify the hosts file. There are also many versions of the hosts uploaded over the Internet. I have tested many versions and I have tried one of them, however, you need to add many domain name and IP resolution mappings. The efficiency is still very high because of repeated test cases. In addition, both Windows and MAC systems can solve this problem.
