AIDebugAccessibilityService Class

Minimal AccessibilityService for AI debugging automation.

AccessibilityNodeInfo objects can be in a "sealed" or "unsealed" state. Sealed nodes have their properties fully populated and accessible, while unsealed nodes may throw IllegalStateException when properties are accessed. This service uses safe accessor methods and sealing utilities to ensure consistent behavior regardless of node state.

See also: AIDebugToolsFeature for the same patterns used in panel-based accessibility traversal.

This service enables text/ID-based UI element clicking for Jetpack Compose panels. When an AccessibilityService is active, Android's accessibility framework fully populates the accessibility tree, including Compose's semantic nodes which are otherwise lazy-loaded.

Enable via:

adb shell settings put secure enabled_accessibility_services
    com.meta.spatial.debugtools/.AIDebugAccessibilityService
adb shell settings put secure accessibility_enabled 1

Commands are received via broadcast:

<ul><li>Action: com.meta.spatial.debugtools.ACCESSIBILITY_COMMAND</li><li>Commands: find_element, click_element, get_all_elements</li></ul>
