Android Studio project files not showing up

I had to Sync Project with Gradle Files in Android Studio to get my files back after they disappeared in Android Studio's Project window.

Go to File > Project Structure > Project Settings > Modules.

Click on the green colored + and add new module. select Application module and set the content root to your project module.

Click next and then finish.

This should do the trick and the complete project structure will appear. It worked for me.

Try Import Project... and navigate to your project. Select build.gradle file.

Be sure to wait for a while, so that android studios can load all your stuff. Sometimes a restart will help, but since you reinstalled it, that shouldn't be the problem.
