问题
I have created a new project in android studio and the app folder is missing. I need to resolve dependencies in build.gradle which is located inside the app folder.

You have selected multiple form factors for your app like below.
That's why it's showing mobile and wear folders instead of app. So, now just double click on mobile folder you will get app level build.gradle file. Same thing for the wear folder.
If you want only mobile app development then you don't have to select wear form factor while creating the project. Then you only get app folder in your project.
