Android App

The Svarla Android app is a native Kotlin client built with Jetpack Compose and Material 3. It connects to the server for signaling and to the MediaBridge for WebRTC audio.

Installing

Obtainium (recommended)

The easiest way to install and keep Svarla updated is with Obtainium, which tracks GitHub releases and notifies you of updates.

1. Install Obtainium from F-Droid or their GitHub releases.
2. Add a new app with the URL: https://github.com/packetmoose/svarla
3. Obtainium will find the APK from releases and install it.

Manual APK download

Grab the latest APK directly from GitHub Releases.

Building from source

If you want to build the app yourself:

cd android
./gradlew assembleDebug
# APK → app/build/outputs/apk/debug/app-debug.apk

Requires JDK 17 and Android SDK platform 34. Or build without any local SDK using Docker:

docker build -f android/Dockerfile.build -t svarla-android-builder android/
docker run --rm -v "$(pwd)/android/output:/output" svarla-android-builder

Connecting to the server

On the login screen, enter:

• Server URL — Your server's address (e.g. https://phone.example.com or http://192.168.1.50:3000)
• Password — The password set via INITIAL_PASSWORD

The app registers the device, syncs history via WebSocket, and is ready to make calls.

Requirements

• Android 8.0+ (API 26)
• Network access to the server (port 3000 or 443)
• Network access to the MediaBridge (port 10443)
