I was facing problem while downloading 3rd party plugins for Android SDK.
Following was the error I was facing –
“Failed to fetch URL https://dl-ssl.google.com/android/repository/addons_list-1.xml,
reason: Connection to https://dl-ssl.google.com refused”
Following is the solution -
Go to the SDK Manager (Navigate to it on the computer, not from eclipse), then open it up and provide proxy. Also check the checkbox which says force http connection for https urls.
(I was behind a proxy.)
