问题
I am trying to setup development environment for Android development. While adding Android ADT plugin in eclipse, I get following error:
Fetching https://dl-ssl.google.com/android/repository/addons_list-1.xml Failed to fetch URL https://dl-ssl.google.com/android/repository/addons_list-1.xml, reason: Unknown Host dl-ssl.google.com Fetched Add-ons List successfully Fetching URL: https://dl-ssl.google.com/android/repository/repository-5.xml Failed to fetch URL https://dl-ssl.google.com/android/repository/repository-5.xml, reason: dl-ssl.google.com Done loading packages.
Could someone guide me easily that how to get rid of this error?
回答1:
I had the same problem.
In the Tools>Options menu in Android SDK Manager, I set the HTTP Proxy Server and HTTP Proxy Port values (I used the same settings that for my internet browser).
That fixed the problem for me !
回答2:
In the Tools>Options menu check the option
Force https://... sources to be fetched using http://
回答3:
You may be having the problem cause you are on a network where Proxy server and proxy ports are used for intercommunication between devices. Set the appropriate proxy server and port number in Tools -> Options. If its still not working then go for
Force https://... sources to be fetched using http://
