Behind the App

RadioHub was born from a simple personal frustration: I wanted a radio app for Android that wasn’t cluttered with intrusive ads, giant banners, or sneaky background trackers. The public, community-maintained directory of radio-browser.info was the perfect starting point to access over 30,000 global stations, but building a reliable, high-quality stream player on top of community-run servers proved to be a fascinating engineering challenge.

The first technical hurdle was reliability. Since we are relying on a community API, we couldn’t just trust a single server endpoint. I implemented a Kotlin HTTP client using Ktor that performs a dynamic, seamless failover between 4 API mirror servers. If a server is slow or goes offline, the app switches to another node in milliseconds, ensuring that searching or exploring categories remains completely uninterrupted for the user.

The second obstacle was real-time audio playback and audio effects processing in the background. Integrating ExoPlayer (Media3) with android.media.audiofx.Equalizer required careful tuning: Android’s audio effects API is notorious for causing metallic pop or click sounds if enabled abruptly. I developed a reactive controller that delays the equalizer setup until ExoPlayer’s audio session ID is fully initialized, and maps decibel levels to millibels smoothly in real time without locking the main thread. Additionally, strict integration with MediaSession ensures audio playback remains solid, allowing users to control the radio from their lock screen or headsets natively.
