Accessibility Service API Disclosure (Focus Bridge):
This app uses Android's AccessibilityService API for the "Focus Bridge" feature. This is a core accessibility tool designed specifically for blind and visually impaired users.
Focus Bridge scans the active window to detect interactive elements (like unlabeled buttons or custom controls that screen readers like TalkBack cannot read) and places a clean, focusable numbered overlay directly over them.
How Focus Bridge uses the Accessibility Service API:
- Screens the active window to find interactive regions, buttons, and text fields.
- Places a focusable overlay with spoken descriptions indicating the label, role, and position of each control.
- Dispatches gestures, long presses, or text inputs to the underlying elements when a user selects a badge.
- Allows users to save custom labels for unlabeled buttons on their device.
- Provides quick activation via shortcuts, notifications, or a Quick Settings tile.
What the Accessibility Service API does NOT do:
- It does NOT collect, store, or transmit screen content or personal user data off the device.
- It does NOT record audio, phone calls, or background conversations.
- It does NOT change system settings or restrict app uninstallation.
- It does NOT automate tasks; every interaction requires explicit user action.
This feature is strictly a utility to enable independent navigation across otherwise inaccessible screens.
Many more features are coming soon!
