Android : git - add remote to Android Studio imported project

I've got some code that I imported into Android Studio.

It's now got a Gradle build (which it didn't have previously). I now need to do a git pull. However, given the directory structure has changed slightly I'm not sure how to go ahead with this.

The Android Studio directory structure under app/src/main looks similar to the original, e.g.:

Android Studio

[main]$ ls
AndroidManifest.xml assets          java            res
[main]$ ls java/
LICENSE.txt README.md   com

The original

$ ls
AndroidManifest.xml README.md       res
LICENSE.txt     assets          src
$ ls src/
com

Under com it's pretty similar.

Any suggestions?
