Check my solution, It will work.
Solutions:
First Download Subversion 1.8.13 ( 1.8 ) Download link ( https://www.visualsvn.com/downloads/ )

Then unzipped in a folder. There will have one folder "bin".
Then
Go to settings - > Version control -> Subversion
Copy the url of your downloaded svn.exe that is in bin folder that you have downloaded.

Don't forget to give the end name like svn.exe last as per image.
Apply -> Ok
Restart your android studio now.
Happy Coding!
