Quick Start

git clone https://github.com/darksoon/RadioWave.git
cd RadioWave
chmod +x gradlew
./gradlew :build-logic:build
./gradlew assembleDebug

Local Builds

# Full build
./gradlew build

# Lint + tests
./gradlew lint
./gradlew test

# Install debug APK
./gradlew installDebug

# GitHub-flavor debug build
./gradlew :app:assembleGithubDebug

# Play Store debug build
./gradlew :app:assemblePlayDebug

Restricted Networks / Proxy

If Gradle downloads are blocked, use a mirror or proxy:

# ~/.gradle/gradle.properties
systemProp.http.proxyHost=<proxy-host>
systemProp.http.proxyPort=<proxy-port>
systemProp.https.proxyHost=<proxy-host>
systemProp.https.proxyPort=<proxy-port>

Release Signing

Signed release builds are handled through GitHub Actions.

• For GitHub/direct download use the signed github APK
• For Google Play distribution use the signed play App Bundle (.aab)

For local signing experiments only:

cp keystore.properties.example keystore.properties
# edit keystore.properties

Installation

Google Play

Install RadioWave from Google Play:

https://play.google.com/store/apps/details?id=de.darksoon.radiowave

GitHub APK

1. Open the latest release page: https://github.com/darksoon/RadioWave/releases/latest
2. Download the current APK asset.
3. Allow installs from unknown sources if your device asks for it.
4. Open the APK and install it.

Player Improvements

• Short network interruptions are handled more gracefully with improved reconnect tuning
• The playback timer now reflects actual listening time and pauses during buffering
• Fullscreen player includes a share action and a sleep timer
• Favorites can be reordered more easily from the favorites screen
• Active Chromecast sessions can be started directly from the fullscreen player, station changes are handed over to TV, and in-app play/pause controls route to the cast device

Android Auto

• Browse is optimized for in-car usage: Favorites, Quick Access, Top Stations, Genres
• Quick Access combines favorites and recents
• Search merges local and remote results more robustly
• Previous/next in the car player now works as real station navigation
• Browse/search callbacks run asynchronously so Android Auto is not blocked by repository or network work
• The player only holds the WiFiLock while the active network is Wi-Fi; WakeLock stays active for stable playback

Chromecast / Google Cast

• Cast devices can be selected directly from the fullscreen player
• Starting a cast session moves the current station to TV and stops parallel phone playback
• Changing stations while casting updates the TV stream instead of starting a separate local stream
• In-app play/pause controls work on the active cast session
• The player UI shows when playback is currently running on TV
• Alexa / Echo streaming is not part of this cast integration and would require a separate Amazon-specific solution

GitHub Actions

Manual Android Build

Available under Actions -> Manual Android Build -> Run workflow.

PR CI

• Runs automatically on pushes and pull requests to main
• Can also be started manually
• Uses Gradle build cache plus configuration cache
• Test-task gating is configuration-cache-safe, so CI no longer breaks on modules without unit tests

Release Build

• Signed releases are created through Actions -> Release Build
• The workflow:
  • updates app.versionName and app.versionCode
  • builds a signed Play APK plus a Play Store App Bundle (.aab)
  • creates a tag and GitHub release
  • uploads release assets, including native debug-symbol artifacts for Play Console troubleshooting
• Workflows are prepared for the GitHub Actions Node 24 migration (actions/checkout@v5)

Privacy

• No analytics
• No ads
• No hidden telemetry
• Crash reports are stored locally only and shared explicitly by the user
