Issue:
When using New Activity wizard, ADT 20 asked to install Android Support library version 8 even though version 9 has been installed.
Pressing "Install/Update" then ADT popup a window downloading Support library, when finished nothing happen.
Pressing "Check Again" does nothing.
If i restarting Eclipse again this problem.
Notice: If you install new version ADT or update via SDK Manager, open SDK Manager standalone and close Eclipse.
Workaround:
- Close Eclipse
- Open SDK Manager standalone (c:\Program Files\Android\android-sdk-windows\SDK Manager.exe)
- Check the checkbox and uninstall Extras -> Android Support Library.
- Check again Extras -> Android Support Library and install it
- Restart Eclipse
- Try to create new project
