Answer by basileus for How do I completely remove Git from an Android Studio project?

What I have done to remove Android Studio project binding to GitHub is:

1. I removed project on https://github.com first (you do not have to remove your project from GitHub though. Treat it as optional step)
2. To remove GitHub binding to Android Studio project you need to go in Android Studio to File -> Settings -> Version Control. But DO NOT expand it, just mark it. Then, on the right hand side change, Git to None (red arrow on the picture below indicate this)
3. Finally remove hidden directory .git from your Project directory, this one which is specified in the picture below (I actually blurred mine :-) ).

Follwoing this three steps I were able to completely re-create fresh project on Github with the same Android Project.

What I do not like in the first answer (and I am not allowed to send comments yet) is that actually removes Github account, but do not remove binding between project in Android Studio and Github.

EDITIn newer version of Android Studio (i.e. Flamingo), in bullet (2) you need to go to:Settings -> Version Control -> Directory Mappings
