Edge gesture and shortcut utility designed for faster mobile navigation.

EdgeFlow is an Android gesture helper that turns the left and right screen edges into configurable one-handed action zones. It is designed for Android users who want faster access to navigation, notifications, media controls, volume controls, screenshots, accessibility shortcuts, and app launchers.

Project Overview

EdgeFlow displays subtle edge handles and uses an accessibility service to turn hold-and-swipe gestures into system actions. The app ships with six fixed edge zones, five circular-menu slots per zone, local settings storage, and generated Google Play graphics.

No hosted demo is configured. The app must be installed on an Android device or emulator to try the gesture and accessibility-service workflow.

Key Features

• ⚡ Six ergonomic edge zones split across the left and right screen edges.
• 🎛️ Five-action circular menus for each edge zone, with 30 default shortcuts.
• 🧭 Accessibility-service actions for Back, Home, Recents, notifications, quick settings, and more.
• 🎨 Adjustable visual handles with color, width, transparency, and touch-feedback controls.
• 📳 Optional haptic feedback for gesture arming and action execution.
• 🗃️ Local Room persistence for zones, menu items, and recent gesture activity.
• 🧪 Robolectric and Roborazzi tests for app behavior and Play Store assets.
• 🖼️ Generated Google Play screenshots, app icon, feature graphic, and listing copy.

Architecture Overview

Components And Layers

MainActivity hosts the Jetpack Compose setup, permission flow, settings screens, simulator view, and zone customization UI. It observes repository state and guides the user toward overlay and accessibility permissions.

EdgeOverlayService is the accessibility service declared in AndroidManifest.xml. It creates the edge overlays, recognizes hold-and-swipe gestures, renders the circular menu, and executes the selected Android action.

EdgeFlowRepository is the state boundary for the app. It stores zone and menu data in Room and persists visual or feedback preferences in SharedPreferences.

Request And Data Flow

1. The user grants display-over-other-apps and accessibility permissions.
2. The accessibility service creates edge handles based on repository settings.
3. A hold-and-swipe resolves the touched zone and opens the zone's five-item circular menu.
4. Releasing over a menu item executes the selected action and records a local activity entry.
5. Compose screens observe repository flows so settings and activity stay current.

Design Patterns

EdgeFlow uses repository-based state access, Room DAOs, Kotlin sealed classes for gesture actions, Compose state collection, and service-owned system-action execution. The UI configures behavior while the accessibility service owns runtime overlay and action work.

Tech Stack & Libraries

Configuration

Android build configuration lives in app/build.gradle.kts. It defines package com.michael.edgeflow, min SDK 24, target SDK 36, version code 9, version name 1.0.2, debug signing, and release signing.

Dependency and plugin versions are centralized in gradle/libs.versions.toml. Runtime user preferences are stored in SharedPreferences under edgeflow_preferences and can be changed through the app UI.

Default zones and menu actions are defined in app/src/main/java/com/michael/edgeflow/model/DefaultEdgeConfiguration.kt. Changing these defaults requires a rebuild and reinstall for fresh installs; existing local data may preserve user edits.

Accessibility-service metadata lives in app/src/main/res/xml/accessibility_service_config.xml. Manifest permissions are declared in app/src/main/AndroidManifest.xml.

Usage / Quick Start

Run The Android App

Build and install the debug variant:

./gradlew installDebug

Then enable the required device permissions:

Settings > Apps > Special app access > Display over other apps > EdgeFlow
Settings > Accessibility > EdgeFlow Gesture Controller

After permissions are enabled, hold on a left or right edge handle, swipe inward, keep holding, and release over a circular menu item to trigger the selected action.

Generate Play Store Assets

Regenerate store graphics with the Roborazzi-backed Gradle task:

./gradlew generatePlayStoreAssets

Build A Release APK

Set signing secrets, then assemble the release variant:

KEYSTORE_PATH=/absolute/path/to/my-upload-key.jks \
STORE_PASSWORD=your-store-password \
KEY_PASSWORD=your-key-password \
./gradlew assembleRelease

API Reference

Not applicable. EdgeFlow is an Android application with a local accessibility service and local Room database. This repository does not define public HTTP endpoints, a public SDK, or a command-line API.

Testing

Run JVM unit tests, Robolectric tests, and non-screenshot Compose tests:

./gradlew testDebugUnitTest

Run connected Android tests on an emulator or physical device:

./gradlew connectedDebugAndroidTest

Regenerate Roborazzi Play Store screenshots and graphics:

./gradlew generatePlayStoreAssets

Tests live under app/src/test/java/com/michael/edgeflow/ and app/src/androidTest/java/com/michael/edgeflow/. Test files use the *Test.kt naming convention, with

Coverage reporting is not configured in this repository.

Deployment

Android

Debug builds:

./gradlew assembleDebug

Release builds:

KEYSTORE_PATH=/absolute/path/to/my-upload-key.jks \
STORE_PASSWORD=your-store-password \
KEY_ALIAS=upload \
KEY_PASSWORD=your-key-password \
./gradlew assembleRelease

provide a privacy policy URL in Play Console under App content.

Docker and docker-compose are not configured because this is a native Android project.

Privacy Policy

Not configured in this repository. Google Play still requires a hosted privacy policy URL before release, but no deployable privacy-policy site is tracked in this app repository.

Health Check

Not applicable. EdgeFlow is installed locally on Android devices and does not expose a server health endpoint.
