Jetpack Camera App (JCA) is a camera app, focused on features used by app developers, and built entirely with CameraX, Kotlin and Jetpack Compose. It follows Android design and development best practices and it's intended to be a useful reference for developers and OEMs looking to validate their camera feature implementations.
This project uses the gradle build system, and can be imported directly into Android Studio.
Currently, Jetpack Camera App is built using the Android Gradle Plugin 8.4, which is only compatible with Android Studio Jellyfish or newer.
JCA is built with modern android development (MAD) principles in mind, including architecture and testing best practices.
The app is split into multiple modules, with a clear separation between the UI and data layers.
Thorough testing is a key directive of JCA. We use Compose Test and UI Automator to write instrumentation tests that run on-device.
These tests can be run on a connected device via Android Studio, or can be tested on an Android Emulator using built-in Gradle Managed Device tasks. Currently, we include Pixel 2 (API 28) and Pixel 8 (API 34) emulators which can be used to run instrumentation tests with:
$ ./gradlew pixel2Api28StableDebugAndroidTest and
$ ./gradlew pixel8Api34StableDebugAndroidTest
