Windows 10, Android Studio v3.6 and v4.0. I also recommend that you then change AS settings to not open the last project on Startup ( Settings -> System Settings -> Reopen projects on startup) If this was the problem, AS will now go into a long update and restart cycle to repair itself, but will end with success.

To fix, just startup Android Studio and then close the current project ( File -> Close Project). TL DR This is sometimes caused by Windows registry settings retained with the current AndroidStudio project. I uninstalled Android Studio include User setting and reinstalled it.(There is no such thing that I can select previous version kind of thing.) But the result is the same. "C:\Users\XXX\AppData\Local\Android\Sdk" does not exists. Some people on Stack-overflow suggested to download SDK separately, but their links just show Android Studio installer, which I already installed. (Updated to 3.3.1, but failed to Sync SDKs ERROR.) I can't install any versions with "Your Android SDK is missing, out of date, or corupted." error. I can't see 'SDK' when I install Android Studio from here. So, I recovered it with removing all the applications and just kept my personal files.Īnd I downloaded and installed Android Studio again, and SDK missing problem occurred like below:

I had a USB connection problem when I debug and updated BIOS then, the laptop had problem with drive so, I needed to recover it.
