Smart Island is a modern, open-source implementation of Android's Dynamic Island experience. It transforms notifications, media playback, incoming calls, timers, charging status, and other live activities into a beautiful floating island with smooth animations and a premium user experience.
See the codeA lightweight, privacy-first Android overlay that turns notifications, calls, media playback, battery states, timers, stopwatches, and system activities into a floating glanceable Dynamic Island.

Smart Island is an open-source Android application that renders a fluid, dynamic floating pill near your device's camera notch or status bar. It intercepts system notifications, live activities, media playback, calls, charging events, hotspot connections, navigation instructions, timers, stopwatches, and battery alerts locally—expanding into rich interactive cards with zero cloud tracking.
The project is designed to be 100% transparent, hackable, and privacy-conscious: all notification processing and history storage are strictly on-device, preferences are stored in local DataStore, and network access is solely opt-in for in-app release checks.
| Feature Area | Capabilities & Details |
|---|---|
| Material 3 Expressive UI | Modern MD3 color tokens, dynamic wallpaper color adaptation (Android 12+), rounded shapes, and fluid physics. |
| Ultra-Fluid Spring Physics | iOS-grade synchronized spring curves (stiffness = 520f, dampingRatio = 0.72f), snappy 190ms cross-fades, organic companion bubble pops, and tactile button bounce. |
| Tap Anywhere to Open App | Tapping anywhere on expanded notification and music cards outside interactive buttons launches the source app and collapses the island. |
| Auto-Hide Pill Inactivity Timer | Automatically hides the pill and companion bubble after a customizable inactivity timeout (1s to 60s with 1-tap presets), with tap-to-awaken gesture. |
| Landscape Mode Control | User toggle to keep Smart Island visible in landscape orientation with automated screen width repositioning, or auto-hide for distraction-free gaming and video. |
| Island Opacity & Transparency | Continuous background opacity slider (20% to 100%) with 4 quick 1-tap presets (Solid, Dark, Glass, Clear) and ambient drop shadow rendering. |
| Inline Reply & IME Focus | Direct text reply input right inside the expanded Island notification card with dynamic WindowManager focus switching, soft keyboard integration, and RemoteInput dispatch. |
| Timer & Stopwatch Modes | Intelligent clock notification parsing for Google Clock, Samsung Clock, MIUI/HyperOS, ColorOS, and Huawei Clock. Collapsed countdown/elapsed badges, expanded circular/linear timer progress, live millisecond stopwatch ticker, and interactive pause/resume/lap/reset controls. |
| Virtualized Notification History | Ultra-smooth LazyColumn virtualized SQLite history log with background AppIconMemoryCache, search bar, app filter chips, full message inspection dialog, and bulk Delete by App support. |
| OEM Device Rules Engine | Tailored background protection and autostart management for Xiaomi/HyperOS, Samsung OneUI, OnePlus/Oppo/Realme (ColorOS/OxygenOS), Huawei/Honor, Vivo/iQOO, and Asus to prevent aggressive background kills. |
| In-App GitHub Release Checker | In-app GitHub update checks and changelog insights with an explicit user toggle (allowNetworkChecks) and strict offline mode fallback. |
| Full-Color App Icons | Extracted launcher icons with LRU caching for crisp, authentic app icons in both collapsed pill and expanded cards. |
| Battery Modes (Low & Saver) | Dynamic Battery island displaying Green for Charging, Pulsing Red for Low Battery (≤ 20%), and Warm Amber for Battery Saver ON with live battery percentage badge. |
| 5-Gesture Control Engine | Complete intuitive gesture system: Single Tap, Quick Swipe Up, Hold + Swipe Up (300ms haptic), Swipe Down (Floating window), and Horizontal Swipe Left/Right with responsive interactive guides. |
| Split Island Multi-State | Secondary auxiliary bubble for concurrent background activities (e.g. Music + Hotspot, Call + Bluetooth, Timer + Music). |
| Wavy Music Player | Real-time audio waveform scrubber, ambient album artwork background glow, track metadata, and dynamic color customization. |
| Message Sync Suppression | Automatically filters background message polling notifications (e.g. Snapchat, WhatsApp sync) to prevent download mode hijacking. |
| Live Activity Tracking | Real-time delivery and rideshare tracking (Uber, Swiggy, Zomato, Blinkit, Rapido, Ola) with brand colors. |
| Turn-by-Turn Navigation | Live turn navigation indicators, maneuver direction arrows, remaining distance, and ETA. |
| Download & Upload Progress | Real-time transfer speed meters (MB/s), progress bars, and animated icons. |
| Wi-Fi Hotspot Monitor | Live tethering client counter, SSID badge, data usage, and quick turn-off action. |
| Flashlight & Screen Recording | Active torch toggle card and live screen recording timer overlay. |
| App Shortcuts Launcher | Quick-launch grid with up to 8 pinned apps or auto-filled recent applications. |
| Custom RGB Color Studio | Fine-grained Red, Green, Blue slider color picker with live Hex preview for all 13 dynamic modes. |
| Notch & Layout Presets | Instant 1-tap calibration for Center Hole, Wide Island, Left Corner, Right Corner, and Compact Pill. |
| Precision Sizing Controls | Millimeter-accurate sliders for Width, Height, X Offset, Y Offset, Corner Radius, and Drop Shadows. |
| Shizuku 1-Tap Auto Setup | Automated permission grants for Restricted Settings, Usage Access, Overlay, and Battery Optimization. |
| Lock Screen Privacy Guard | Opt-in lock screen display with customizable sensitive content hiding (App Icon Only vs Full Preview). |
Smart Island intelligently categorizes and presents live activities into 13 dedicated modes:
Smart Island features a comprehensive gesture engine to manage notifications, multitasking, and media effortlessly:
| # | Gesture | Action | Instructions & Feedback |
|---|---|---|---|
| 1 | Single Tap / Click | Expand & Collapse | Tap once on the collapsed pill to open rich details; tap anywhere on the screen background to collapse back. (Cutout region remains active when idle-hidden) |
| 2 | Quick Swipe Up | Dismiss Current | Touch the expanded card and flick upward by ≥ 48dp to dismiss the active notification from the stack. |
| 3 | Hold + Swipe Up | Clear ALL Notifications | Press & hold the expanded card for 300ms until a haptic vibration pulse occurs, then swipe up to dismiss all pending notifications simultaneously. |
| 4 | Swipe Down | Floating Window | Drag downward by ≥ 48dp on the expanded card to launch the application into a freeform floating window overlay. (Requires Shizuku or OEM freeform) |
| 5 | Swipe Left / Right | Switch Notification Stack | Swipe horizontally across expanded cards to navigate smoothly between multiple active notifications, timers, and media sessions. |
