Project import from github into android studio says it is not a gradle project

As the title says, I imported the project I was working on from github to android studio. It has build.gradle files and settings.gradle. Why isn't it a gradle file?

Am I missing something I needed to do when I pulled it from github? I just followed android studio import from github option. What else do I need to do ...?

When I try to do gradle sync, it tells me that the project is not based on gradle.
