I downloaded the
Android SDK Manager
Failed to fetch URL https://dl-ssl.google.com/android/repository/repository-7.xml, reason: SSLPeerUnverified peer not authenticated
Try using "http" instead of "https".
Go to the
Android SDK Manager -> Tools -> Options... and check
"Force https://... sources to be fetched using http://...".
Also, you can set your proxy settings, if any.
