Detailed StackOverflow Answer

This usually happens when you're opening someone else's project after unzipping it and your current Android Studio Version is older to the version the project was compiled in.

The way to solve it is

Go to Help and about to see your android studio version
go to File>Project Structure> and set your Android Gradle Plugin version to your android studio version
Change the Gradle version to the one you usually use.

Build the project and it should run without any errors

You can try this.
