Version 2.4

Version 2.4.0-alpha01

June 26, 2024

androidx.test.uiautomator:uiautomator:2.4.0-alpha01 is released. Version 2.4.0-alpha01 contains these commits.

API Changes

  • Deprecated Configurator#getKeyInjectionDelay and setKeyInjectionDelay as the parameter is unused now that text is always injected directly rather than by key presses. (I3bcc5).

Bug Fixes

  • Updated the delay between UiObject2 motion events to account for dynamic refresh rates (i.e. Smooth Display) (I43f12).
  • Reduced flakiness from accessibility node staleness on certain UIs by periodically invalidating the accessibility cache (I3be25).
  • Fixed StaleObjectExceptions occurring when calling toString or hashCode on a stale UiObject2. (I38ea1).
  • Improved UiWatcher performance by skipping unnecessary waitForIdle calls. (I8c65e).
  • Fixed javadoc inaccuracies, especially to clarify when each Configurator parameter is used. (Ie10b1, I71631).

Version 2.3.0

Version 2.3.0

February 21, 2024

androidx.test.uiautomator:uiautomator:2.3.0 is released. Version 2.3.0 contains these commits.

Important changes since 2.2.0

  • Multi-display support: Added support for finding and operating on objects across multiple displays, and UiDevice methods to manage secondary displays (Ie6544, I912cd).
  • New selectors:
    • Added By.displayId to select objects by their display ID (I1825b).
    • Added By.hasParent and By.hasAncestor to select objects according to their parents (I93c36).
    • Added By.hint methods to select objects by their hint text (Idd345).
  • Custom conditions: Exposed a Condition interface to support custom wait conditions, and added corresponding UiDevice#wait, UiObject2#wait, and UiObject2#scrollUntil methods (27c0ea, 099d6e).
  • Bug fixes and reliability
    • Fixed an issue where the display size calculations were occasionally incorrect and might ignore portions of the screen (Ifc016). Coordinates and offsets used in tests may need to be adjusted.
    • Updated MotionEvent injection to improve accuracy (678ca3) and better emulate user gestures (454450).
    • Improved the reliability of scrolls (I7b059), rotations (c6cea0), long clicks (49572b), pinches (3c619a), and more.
