how to add advertisement my cell phone

I hope you are doing well

In order to insert advertisements in my first app, I have to insert two strings of code into the build.gradle file and the app's source code. It appears, however, that the build.gradle file or folder does not exist in my file.Could you please tell me how to integrate ad mob into my app?

Does anyone know how to do it?
