Kotlin / Swift Audio Plugin

@Microlent

Hi there, I understand the goal: a native background-audio plugin for iOS Swift and Android Kotlin that runs continuously, survives minimisation or lock, supports online plus offline streaming, exposes full transport controls, updates metadata in real time, and syncs playback status with your web app. The plugin must feel as solid as a native streaming app and mirror your existing online player’s behaviour. What I’ll build * Stable background audio sessions on iOS plus Android * Continuous playback up to 1 hour with background network fetching of audio chunks * Real-time metadata plus playback-state updates to your web app when online * Lock-screen or notification controls: play, pause, skip, seek * In-app player UI: title, artist, cover art, chapters, progress bar, seek, auto-pause * Mini-player that persists across screens * Offline-capable caching layer for smooth playback I’ve built similar native modules for streaming plus background services, including lock-screen controls, media sessions, and online or offline sync. Quick questions before I send timeline and milestones 1. Does your online player provide chunked streaming endpoints or raw audio URLs 2. Should offline mode cache full tracks or limited rolling buffers 3. Are you using React Native or Flutter or Capacitor, or is this plugin integrated into a fully native app Once I have these answers, I’ll estimate timeline and cost. Best regards, Jenifer

Hello, I can deliver a rock-solid native Kotlin/Swift audio plugin behind a single, easy-to-call interface for your music-streaming app. It will keep audio playing smoothly in the background on both iOS and Android, survive minimization or device lock, expose transport controls on the lock screen and notification shade, update track metadata in real time, and play nicely with other audio sources to avoid unexpected interruptions. Efficiency and battery friendliness are built in. Here's my approach: two slim native modules (Swift for iOS, Kotlin for Android) plus a lightweight bridge layer that exposes a unified API. On iOS I’ll configure AVAudioSession for background playback, use Now Playing info, and hook up remote-control events. On Android I’ll use MediaSession, handle AudioFocus, and provide stable notification controls. The bridge will keep data flow clean with a small, well-documented API surface your front-end can call to play, pause, seek, and push metadata. I’ll provide a minimal demo app that shows continuous playback with smooth hand-off between components. I’ll run tests on the latest iOS and Android releases and share a straightforward roadmap and docs. Timeline: MVP ready in about 4 weeks, with a polished demo by then and optional refinements afterward. Budget: 650 CAD. I can point you to similar audio-module work if helpful. What is the exact public API surface you want for the front-end to call (function names, events)? Any specific background-audio requi

Hi there, I understand you need a robust audio plugin built in Kotlin/Swift, with smooth playback, low-latency processing, and full compatibility across modern Android and iOS versions. I’ve worked on audio engines, DSP modules, and custom audio features (recording, effects, waveform rendering, streaming), so I’m confident delivering a polished, performant plugin that integrates cleanly into your existing app. Before I begin, could you clarify two key points: Do you already have an existing audio engine or are we building from scratch? What specific audio features you need (effects, processing, EQ, recording, timestretch, etc.)? Ready to get started as soon as I receive these details.

Hi there, I can develop a robust native background-audio plugin for both iOS (Swift) and Android (Kotlin) that mirrors your web player’s functionality and exposes a single, easy-to-call interface. The plugin will support continuous background playback for up to an hour, survive app minimisation/lock, manage audio sessions correctly, and provide full transport controls via lock-screen and notification panels. I’ll implement real-time metadata updates, smooth buffering of online audio chunks, and optional offline playback with proper caching logic. The plugin will also sync track status, timeline, and playback position with your web app whenever the device is online. On the UI side, you’ll get a full in-app player (title, artist, cover art, seek bar, play/pause, chapter switching, auto-pause) plus a persistent mini-player for seamless control across the app. I’ll ensure proper handling of audio interruptions, battery-friendly behaviour, and clean integration with your front-end and backend flow. Estimated timeline: **3–4 weeks** including testing on the latest iOS/Android versions. I’ve built similar native modules for podcast and audiobook apps with background playback, offline caching, and system media controls—happy to share examples upon request. Kind regards.

Hi I can build a rock-solid native audio plugin with Swift (iOS) + Kotlin (Android) that keeps streaming smooth in the background, exposes lock-screen/notification controls, and syncs state back to your web app through one unified interface. The main technical risk here is background network + playback reliability (OS throttling, audio focus interruptions, and buffering gaps), so I’ll implement proper session/focus handling, resilient buffering with offline cache, and a foreground/now-playing architecture that survives lock/minimize. On iOS I’ll use AVAudioSession + background audio mode with Now Playing + remote command center, and on Android I’ll use a Foreground Service + MediaSession + ExoPlayer for stable playback and metadata updates. The plugin will support online/offline playback, background prefetch of audio chunks, and real-time event streaming to your web app (status, timeline, position) when connectivity is available. I’ll also deliver the in-app player UI (mini-player + full player) with seek, chapter changes, and auto-pause rules that mirror your browser player behavior. All controls (play/pause/skip/seek) will be consistent across in-app UI and OS controls, with battery-friendly settings and clean interruption handling. You’ll get a demo app that proves continuous playback up to an hour with seamless handoff, plus clean source and documentation for integrating with your existing online player component. Thanks, Hercules
