In Android studio1.5 version when you try to add the file in your project,
android studio will ask for a pop like "schedule for Addition"
to subversion?. select the check box (Remember, don't ask again) and click "yes".
After this whatever the file you add or remove to your project it will automatically
synced to your svn repository. suppose if you didn't get that dialog, but you want to
add the newly added .png or xml file to svn means you can manually select those files
which you have added (the newly added file will be in red color) right click
on that file -> subversion -> Add to VCS or simply select the file and use (CTRL+ALT+A).
In the image green color(logo_actionbar) represents to file was already added to svn, red represents yet to add in svn. cool..!
If you want to change the "Schedule for Addition" setting means, Go to Settings -> Version Control -> Confirmation -> When files are created
Choose Show options before adding to version control
