问题
My Android SDK manager starts and then tries to fetch new updates. But it can't fetch content and shows following error in log window:
Failed to fetch URL https://dl-ssl.google.com/android/repository/addons_list-1.xml, reason: Connection to https://dl-ssl.google.com refused
I am using windows 7 32-bit and working with Eclipse ADT.

Solutions:
- Starting SDK manager as Administrator
- Starting android.bat from command-line.
- Updating Eclipse ADT from
help/check for updates.
- Disabling windows firewall from
Control Panel\System and Security\Windows Firewall\Customize Settings
- Clearing download catche from tools/options in SDK Manager.
Adding Google's repository website in use-defined site from
tools/Manage Add-on sitesin SDK Manager.
Forcing https// sources to be fetched using http:// in SDK Manager
- If any of above solution does not work then the last solution remained is to disable firewall of your antivirus.
Some antivirus packages like Avast contains their own firewalls that blocks fetching content in SDK manager. You must have to disable antivirus firewall from its settings.

On Linux check that the cache directory exists:
mkdir -p ~/.android/cache
and that you have rights to it:
ls -ld ~/.android/cache/
