These samples showcase different architectural approaches to developing Android apps. In its different branches you'll find the same app (a TODO app) implemented with small differences.
In this branch you'll find:
- User Interface built with Jetpack Compose
- A single-activity architecture, using Navigation Compose.
- A presentation layer that contains a Compose screen (View) and a ViewModel per screen (or feature).
- Reactive UIs using Flow and coroutines for asynchronous operations.
- A data layer with a repository and two data sources (local using Room and a fake remote).
- Two product flavors,
mockandprod, to ease development and testing. - A collection of unit, integration and e2e tests, including "shared" tests that can be run on emulator/device.
- Dependency injection using Hilt.
The app in this project aims to be simple enough that you can understand it quickly, but complex enough to showcase difficult design decisions and testing scenarios. For more information, see the app's specification.
- A template. Check out the Architecture Templates instead.
- A UI/Material Design sample. The interface of the app is deliberately kept simple to focus on architecture. Check out the Compose Samples instead.
- A real production app with network access, user authentication, etc. Check out the Now in Android app instead.
- Intermediate developers and beginners looking for a way to structure their app in a testable and maintainable way.
- Advanced developers looking for quick reference.
To open one of the samples in Android Studio, begin by checking out one of the sample branches, and then open the root directory in Android Studio. The following series of steps illustrate how to open the sample.
Clone the repository:
git clone git@github.com:android/architecture-samples.git
Finally open the architecture-samples/ directory in Android Studio.
