Failed to fetch URL https://dl-ssl.google.com/

After the android SDK is installed, run the android SDK manager to see the solution "failed to fetch URL http://dl-ssl.google.com/android/repository/addons_list" (the URL may be different.

Click search in the Start menu in the lower left corner of the desktop, copy the following path: c: \ windows \ system32 \ drivers \ etc to the search window, and click Search now to find the hosts file, it is actually a plain text file.

1. Open it with notepad

2. Add the 74.125.237.1 dl-ssl.google.com to the last line

3. Save and close the host (provided that you have the permission to modify this file)

I have tried this method and it is absolutely easy to use. You can try it.
The above three steps can basically solve the problem. If there are still problems, please try the following operations:
1. Choose tools> options from the android SDK manager menu.
2. Set the proxy server in the proxy server column.
3. Select two check boxes in the MISC column.
In the final analysis, it means that the Chinese network has lost the Google server, or your network cannot connect to this server. We can try another way to connect it.
