Improve touch target detection and UI layout in the A11y Scanner - #10
Merged
Conversation
- Update `A11yNodeExtractor` to use `touchBoundsInRoot` instead of layout bounds, ensuring that compact components with expanded touch regions (like small chips) are correctly evaluated. - Introduce `MeasurementToleranceDp` (0.01dp) in `TouchTargetRule` to prevent false negatives caused by floating-point rounding errors during coordinate conversion. - Add `windowInsetsPadding` to `ScanSummaryBar` to prevent the summary UI from overlapping with system status bars. - Add unit and instrumentation tests to verify measurement tolerance and expanded touch bound extraction for compact clickable elements.
