private static boolean shouldIgnorePaneChanges(AccessibilityEvent event) {
  if (!BuildVersionUtils.isAtLeastP()
      || (event.getEventType() != AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED)) {
    return false;
  }
  if (event.getContentChangeTypes() == AccessibilityEvent.CONTENT_CHANGE_TYPE_PANE_DISAPPEARED) {
    // The event text is the title of pane being removed.
    return true;
  }

  // . We need to differentiate between pane changes with CONTENT_CHANGE_TYPE_UNDEFINED,
  // and events filed by getDecorView().sendAccessibilityEvent(WINDOW_STATE_CHANGE). The only way
  // I can find is to check whether the source node is null.
  return (event.getContentChangeTypes() == AccessibilityEvent.CONTENT_CHANGE_TYPE_UNDEFINED)
      && !AccessibilityEventUtils.hasSourceNode(event);
