Glyph Torch

A minimal, single toggle utility for Nothing devices. Controls all Glyph LEDs simultaneously with one master toggle.

Built with the Nothing Glyph Developer Kit.

Features

• Single master glyph toggle controls all glyph zones
• Pure monochrome design — AMOLED black / white with red accent
• Edge-to-edge, Nothing-inspired minimal UI
• Automatic device detection (Phone 1, 2, 2a, 2a Plus, 3a, 3a pro...)

Requirements

• Nothing device on Android 14+ (SDK limitation)
• Foreground usage only (SDK restriction)
• Android Studio with AGP 8.11+
• JDK 17

SDK Integration

This project uses the Nothing Glyph Developer Kit:

• Repo: https://github.com/Nothing-Developer-Programme/Glyph-Developer-Kit
• Download KetchumSDK_Community_YYYYMMDD.jar from the sdk/ folder and place it in app/libs/
• The build already includes implementation(fileTree(dir: "libs", include: ["*.jar", "*.aar"]))

Manifest

<uses-permission android:name="com.nothing.ketchum.permission.ENABLE" />

<application>
    <!-- Use "test" for development, replace with your real API key for production -->
    <meta-data android:name="NothingKey" android:value="test" />
</application>

Build and Run

# Build debug APK
./gradlew :app:assembleDebug

# Install on connected device
./gradlew :app:installDebug

Enable Glyph SDK debug mode (recommended for development):

adb shell settings put global nt_glyph_interface_debug_enable 1

Notes

• SDK only works on Nothing devices on Android 14+
• Debug mode auto-expires after ~48h
• Only foreground apps may control glyphs
