Island Recorder

A Xiaomi-focused screen recorder built as a replacement for the stock Xiaomi screen recorder, with device-specific settings integration and Super Island recording controls.

Island Recorder is a personal fork built because the stock Xiaomi screen recorder did not fit my workflow. It is intended as a replacement recorder for supported Xiaomi devices, with local-only recording, flexible video/audio settings, Xiaomi-specific system setting adaptation, and recording controls exposed through Xiaomi Super Island.

This project is not intended for non-Xiaomi devices or Xiaomi devices that do not support Super Island. Core Android recording paths may still compile or run elsewhere, but the product design, privileged integrations, and control surface are optimized for Xiaomi/HyperOS behavior.

This project is developed based on the following projects:

• Leaf-lsgtky/IslandRecoder
• IcradleInnovationsLtd/FluxRecorder

Highlights

• Screen recording: record the device screen through Android MediaProjection.
• Resolution options: native, 1080p, 720p, 480p, and 360p.
• Frame-rate control: auto mode and fixed limits from 15 FPS up to 120 FPS.
• Codec choices: H.264, H.265, and H.265 HDR, with H.265 used as the default fallback.
• Audio sources: no audio, internal audio, microphone, or both.
• Recording controls: foreground notification, Quick Settings tile, and recording state handling for start, stop, pause, resume, and cleanup.
• Super Island controls: recording status and controls are adapted for Xiaomi Super Island on supported systems.
• Floating controls: optional overlay controls remain available while recording.
• Miuix interface: Compose UI built around Miuix components and Xiaomi/HyperOS-oriented visual conventions.
• Xiaomi-specific settings: privileged settings integration for Xiaomi screen recording related behavior.
• Scoped storage: recordings use MediaStore under DCIM/screenrecorder by default, or a user-selected directory through Android Storage Access Framework, without broad storage or media permissions.
• Launcher icon control: optionally hides the launcher icon; settings remain accessible by long-pressing the Quick Settings tile.
• Privacy-first design: no analytics, no telemetry, and no network reporting.

Privileged Features

Island Recorder can work without privileged access for normal MediaProjection-based recording. Some advanced features require Root or Shizuku:

• Show screen touches: temporarily enables Android touch visualization while recording.
• Xiaomi screen share protection control: an independent setting temporarily disables and restores Xiaomi screen share protection around recordings when supported.
• Project media permission grant: grants the app the system project media operation where supported, reducing repeated capture permission friction.
• Xiaomi Focus Island notification bypass: an independent setting temporarily isolates XMSF while posting recording notifications on supported Xiaomi systems.

Privileged operations use binder hook paths through Shizuku or root app_process. Shizuku UserService/AIDL is not used. The selected authorizer is respected, and controls are disabled when that authorizer is unavailable.

Supported Android Versions

• Minimum SDK: 35 (Android 15 based HyperOS 3 only)
• Target SDK: 37

Device Compatibility

Island Recorder is designed for supported Xiaomi/HyperOS devices with Super Island support.

Not recommended:

• non-Xiaomi devices,
• Xiaomi devices without Super Island support,
• ROMs where Xiaomi screen share protection, Focus Island/Super Island, or related privileged settings behave differently.

Root/Shizuku features, Xiaomi privacy protection, Super Island behavior, and project media permission behavior depend on the ROM, Android version, and active authorizer.

Building

Island Recorder is an Android Gradle project.

Prerequisites

• JDK 25 with JAVA_HOME configured correctly.
• Android SDK / Android Studio with the required platform and build tools installed.
• GitHub Packages credentials for the snapshot miuix dependency.

GitHub Packages Authentication

GitHub Packages requires authentication for the Miuix Maven repository. Add your GitHub username and a classic personal access token with the read:packages scope to your global Gradle properties file:

• Linux / macOS: ~/.gradle/gradle.properties
• Windows: %USERPROFILE%\.gradle\gradle.properties

gpr.user=YOUR_GITHUB_USERNAME
gpr.key=YOUR_PERSONAL_ACCESS_TOKEN

Do not commit these credentials to this repository.

Build Commands

For a local debug build:

./gradlew :app:assembleUnstableDebug

For a broader debug build that also covers helper modules:

./gradlew assembleDebug

The app uses the level flavor dimension:

• Unstable: default development flavor with a git hash version suffix.
• Stable: release flavor with the same git hash version suffix.

Technical Overview

• Language: Kotlin
• UI: Jetpack Compose and Miuix
• Dependency injection: Koin
• Settings: AndroidX DataStore
• Recording stack: MediaProjection, MediaCodec, MediaMuxer, AudioRecord, and MediaRecorder
• Privileged integration: Shizuku and root app_process binder hooks
• Modules: :app, :app-process, and :hidden-api

Privacy

Island Recorder is designed to keep recording data local.

• No analytics.
• No telemetry.
• No tracking.
• No remote reporting.
• Recordings and settings stay on the user's device.
• Files leave the device only through an explicit user share or export action.
