- Bug: dragging the bubble panned the OSM map instead of moving the
bubble. The OnTouchListener was attached to the ComposeView, but
the inner MapView consumed ACTION_DOWN for its own pan handling
before the listener fired. Fix: wrap the ComposeView in a custom
TouchInterceptor FrameLayout whose onInterceptTouchEvent always
returns true. Touches go to the wrapper's OnTouchListener; child
views (including MapView) never see them. Bubble is now purely a
visualization — pan/zoom is impossible.
- Drag-to-dismiss: when the user starts dragging (after passing
TAP_SLOP), a translucent dark circle with a white X appears at
bottom-center via a separate WindowManager view. Highlights red
when the bubble's screen-space center is within hit slop of the X.
Releasing on the X tears down the bubble AND fires onDismissed —
DetectionService flips setOverlayEnabled(false) so the toggle and
the bubble state stay in sync. Releasing elsewhere is a normal
drag (just repositions). The dismiss zone uses FLAG_NOT_TOUCHABLE
so it never steals the gesture; it's purely visual feedback.
