When creating a new project with Android Studio, three Gradle files are generated by default. Two of those files, settings.gradle and build.gradle, end up on the top level of the project. Another build.gradle file is created in the Android app module. This is how the Gradle files are placed in the project:
MyApp
├── build.gradle
├── settings.gradle
└── app
└── build.gradleThese three files each serve their own purpose, which we will further look into in the upcoming sections.
For a new project containing only an Android app, settings.gradle looks like this:
include ':app'
The settings file is executed during the initialization phase, and defines which modules should be included in the build. In this example, the app module is included. Single module projects do not necessarily require a settings file, but multimodule projects do; otherwise, Gradle does not know which modules to include.
