Whenever I open a project in Android Studio, I'll see this error:
When I click "Fix it", it will show this window:
I don't know what to do because I'm running TortoiseSVN 1.9.0, which is the latest version.
What should I do to fix this error? Thanks for your help.
It's just misprint: must be "too new"
Android Studio based on Intellij IDEA, Intellij 14.1.4 cannot use svn 1.9.0
Intellij IDEA 14 works with SVN 1.9, it just shows a warning: https://youtrack.jetbrains.com/issue/IDEA-140754
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 .
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.
In my case it was related with broken path:
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Issue was resolved after installing xcode-select:
xcode-select --install
