Documentation
If you are looking for documentation around the companion applications check out the Home Assistant Companion Documentation. This will provide you instructions on using the applications.
Setup App Development Environment
-
Download and install Android Studio
-
Download / clone this repository to a folder on your computer
-
Create a Firebase project at Firebase Console
-
Create four Android apps, with following package names
-
io.homeassistant.companion.android
-
io.homeassistant.companion.android.debug
-
io.homeassistant.companion.android.minimal
-
io.homeassistant.companion.android.minimal.debug
-
Now download the
google-services.json
file and put it in the home-assistant-Android/app folder. This file contains the configuration of the whole project (all the four applications).You can also use the mock services file instead of generating your own The file should contain client IDs for all packages listed above for debugging to work properly. If you do not generate your own file push notification will never work
-
Start Android Studio, open your source code folder and check if the Gradle build will be successful using Build/Make Module "App". You might have to install the right Android SDK via Tools/SDK Manager first.
-
Create keystore containing keypair for debug application signing. In Android Studio: Menu/Build/Generate signed APK, then use a button to create new keystore. Remember the passwords and key alias
-
Set environmental variables used in
app/build.gradle.kts
: -
KEYSTORE_PASSWORD
-
KEYSTORE_ALIAS
-
KEYSTORE_ALIAS_PASSWORD
-
Run the build using
gradlew build
from command line. -
If the build is successful, you can run the app by doing the following: click Run -> Run 'app'
-
Connect your phone or create a new virtual device following on screen instruction
-

If you get stuck while setting up your own environment, you can ask questions in the #devs_mobile_apps channel on Discord.
Push Notifications
If you want to work on push notifications or use a development build with push notifications, please go the server side code HERE and deploy it to your firebase project. Once you have your androidV1 URL to the deployed service, set it in to your ${GRADLE_USER_HOME}/gradle.properties
file, e.g.:
homeAssistantAndroidPushUrl=https://mydomain.cloudfunctions.net/androidV1
You can also define the rate limit function URL, e.g.:
homeAssistantAndroidRateLimitUrl=https://mydomain.cloudfunctions.net/checkRateLimits
App Flavors
The Android app has both a full flavor that uses Google Play Services to offer features like location tracking and notifications. There is also a minimal flavor that does not require Google Play Services and can be found in the releases section. The minimal flavor does not have location tracking or notifications.
Testing Dev Releases
We are using Github Actions to perform continuous integration both by unit testing, deploying dev releases to Play Store Beta and final releases to the Play Store when we release. To help test out a specific feature/fixes users can find the APK on the Actions page for each pull request, this debug APK can be installed side-by-side the production or beta builds.
Quality
We are using ktlint as our linter. You can run a check locally on your machine with:
./gradlew ktlintCheck
This commands runs on our CI to check if your PR passes all tests. So we strongly recommend running it before committing.
To run a check with an auto-format:
./gradlew ktlintFormat
Translating
The project currently uses lokalise to translate the application. If you are interested in helping translate go to the link and click start translating!
Generating a release to production
- Create a new release with the name and tag in the
{MAJOR}.{MINOR}.{PATCH}
format - Steal the release notes from the latest beta build
- This will cause a tag to be added to the project and the
Production Deploy
Workflow will handle the rest - Note: Only the first 500 characters of the release notes get set in the Google Play release
