Android Studio 2.2.2: All packages are not available for download
I was facing the same issue. For me, it got resolved by setting proxy settings.
Android Studio > File > Settings >appearance and behavior> System Settings > HTTP Proxy
I would suggest checking any proxy is required to enable internet for your android studio. Hope this will help somebody.
"Launch Standalone SDK Manager" is not available in newer versions.
Just select "SDK Tools" tab, then "Android SDK Build-Tools and place a check next to 23.0.1, 23.0.2, 23.0.3, etc. and any others you may want to install.
Select Apply and when complete, press Finish.
Rebuild and see if that helps.
