问题
If I choose Tools > Android > SDK Manager from the menu, or click the SDK Manager icon on the tool bar, nothing happens. What can I do to correct the problem?
回答1:
I had the same problem. When checking the {SDK}/tools/android it said it couldn't create a file, and I noticed it was in a location that needed admin approval.
When launching android studio, launch it as administrator then try it. Fixed it for me.
回答2:
Did you check {SDK}/tools/android launch?
回答3:
In my case, after a failed update 0.3 -> 0.59, I had clean-installed (unzipped) the wrong version (update only, which started just fine, but without SDKs), I had to reinstall the bundle version to even have SDK manager.

My sdk manager was working, well, it seems to be working, but as soon as I started to download anything - showed me errors, something like "didnt create directory.." so solution was simple and easy - run as administrator. Or you can just change exe file to run as administrator in properties of this file ;)

Your Path environment variable doesn't contain C:\Windows\System32. Please try adding it and your error will be resolved!

Launch Android Studio as administrator and disable your anti-virus and try again. My comodo internet security was creating the trouble.

For ubuntu users,change the permission of {SDK}/tools/android to read/write for all users
