Where does android studio store its SDKs?

Question

Android

I wanted to see an example from github.com via file-import samples in Android Studio. And then the program began to swear that the path to the sdk was not specified. Yes, I can point to my old sdk, but there is no necessary API there, and downloading via a 32 kb / s modem is too long.
(The studio itself was downloaded for three days)
Where is the sdk stored by default?

Answer 1

if I'm not mistaken, AppData/Local/Android

Answer 2

for the sdk project, you can see File -> Project Structure -> SDK Location
And by default in Android Studio, the sdk api is not loaded

Answer 3

Windows :
C:\Users\user\AppData\Local\Android\Sdk
or:
%LOCALAPPDATA%\Android\sdk
For Linux : ~/Android/Sdk
For Mac : ~/Library/Android/sdk
