Android Studio project files not showing up

Question

I have a library project in Android Studio that has been working fine, but today I went to work on it and all of the files are missing except for a few git files. The folders/files are there when I look in the project's folder on my hard drive, they just aren't displaying in Android Studio. Here is a screenshot:

I tried reinstalling and updating Android Studio, but it didn't work. Any ideas as to what is going on here? How can I fix it?

Answer 1

Go to: File > Sync Project with Gradle files. It will show up all the files linked with the gradle.
