"Subversion command line client version is too old" error in Android Studio
Solution 1
It's just misprint: must be "too new"
Android Studio based on Intellij IDEA, Intellij 14.1.4 cannot use svn 1.9.0
Solution 2
Intellij IDEA 14 works with SVN 1.9, it just shows a warning: https://youtrack.jetbrains.com/issue/IDEA-140754
Solution 3
Svn 1.9 command line client should work in IDEA - just warning (you can close it) is shown. upgrade new version 14.1.5 from https://confluence.jetbrains.com/display/IDEADEV/IDEA+14.1+EAP or 15 EAP: https://confluence.jetbrains.com/display/IDEADEV/IDEA+15+EAP .

Solution 4
As Lazy Badger says, it should say is too new
.
Faced same problem on Debian. I had 1.9 version installed. I fixed it by removing my installed version and then installing 1.8 version:
aptitude remove subversion
aptitude install subversion=1.8.10-6+deb8u1
EDIT
As I understand, the devs of Android Studio have fixed this issue in latest releases.
