Android SDK Manager cannot display a downloadable SDK solution that is not installed

FAQ: i downloaded some SDKs from my Android SDK manager, but now I want to download the new SDK again, I don't see the list of packages? What should I do?

Answer: It is said that Dl-ssl.google.com is strong in the mainland, the great Heavenly Kingdom is really not let people live, the solution is to modify C:\Windows\System32\drivers\etc\hosts File. Add a line:

74.125.237.1 dl-ssl.google.com

It is important to note that the Hosts file is read-only, we do not have permission to modify, we need to copy the Hosts file to the desktop or other places, and then modify.

Then save, copy the modified Hosts file to the C:\Windows\System32\drivers\etc directory, replace the file is good!!! We'll be successful when we download the SDK again.

PS: added, in Mac or Linux, the Hosts file is located in /etc/hostsand can be edited using sudo vim/etc/hosts .
