Code Review

This pull request implements support for reporting expansion state changes to the Android accessibility system for API level 36. It introduces a didChangeExpandState method in AccessibilityBridge to detect changes in expansion flags and dispatches CONTENT_CHANGE_TYPE_EXPANDED events. A new test case verifies these events are sent during state transitions. Review feedback suggests improving code readability by grouping redundant SDK version checks, refining the assertion message in the new test for better accuracy, and adding negative test cases for lower API levels to ensure the version guard works as expected.
