Project structure (app, gradle, manifests) in Android Kotlin - UI Render Trace

Component - Project structure (app, gradle, manifests)

This UI shows the main parts of an Android project structure: the app folder, Gradle build files, and AndroidManifest.xml files. These parts work together to build and run your app.

Widget Tree

ProjectRoot
├── app
│   ├── src
│   │   ├── main
│   │   │   ├── java
│   │   │   ├── res
│   │   │   └── AndroidManifest.xml
│   │   └── test
│   └── build.gradle
├── build.gradle
└── settings.gradle

The root folder contains the app folder and Gradle files. Inside app, the src/main folder holds code (java), resources (res), and the AndroidManifest.xml file. The build.gradle files configure how the app is built.

Key Insight

Understanding the Android project structure helps you know where to put your code, resources, and configuration files. The Gradle files control how your app is built, while the AndroidManifest.xml declares app components and permissions. This structure keeps your project organized and ready to build.
