Now here's a solution, as follows.
1. Launch Android SDK Manager, open the main interface, select "tools", "options...", pop up the "Android SDK manager-settings" window;
2. In the "Android SDK manager-settings" window, fill in port"and 80 in the"http proxy server"and"http proxy mirrors.neusoft.edu.cn input boxes, and select "forc E https://sources to be fetched using http://..."check box. Click the "close" button to close the "Android SDK manager-settings" window and return to the main screen after Setup is complete.
3. Select "packages", "reload".
