Screen Timeout Tile

A lightweight Android app that adds a Quick Settings tile for rapidly switching the system screen timeout between a short preset (30 seconds) and a long preset (10 minutes). The companion activity helps you grant the required permission and shows the currently applied timeout.

Features

• Quick Settings tile labeled "Screen Timeout" with dynamic subtitle showing the active timeout.
• Toggles between 30 s and 10 min using Settings.System.SCREEN_OFF_TIMEOUT.
• Prompts the user for Modify system settings permission when this access is missing.
• Home activity displays permission status, the current timeout value, and a shortcut to the system settings screen.

Getting Started

1. Open the project in Android Studio (Giraffe or newer) with the Android Gradle Plugin 8.13.0 and Kotlin 2.0.21 toolchain.
2. Connect a device or start an emulator running Android 7.0 (API 24) or newer.
3. Run ./gradlew assembleDebug or use Run ▶ Run 'app' in Android Studio to install the debug build.

Using the Tile

1. Launch the app and tap Open system settings to grant "Modify system settings" access.
2. Open Quick Settings, tap the edit/pencil button, and drag the Screen Timeout tile into an active slot.
3. Tap the tile:
   • Without permission: the tile stays inactive and the activity highlights the missing access.
   • With permission: the tile flips between 30-second and 10-minute timeouts and updates its subtitle accordingly.

Testing & Verification

• JVM unit tests: ./gradlew test.
• Instrumented tests (optional): ./gradlew connectedAndroidTest with a device attached.
