Use this skill to drive cross-app and system-UI flows from instrumentation tests using UiAutomator 2.3.0 — `UiDevice`, `BySelector` / `UiObject2` (modern), `UiSelector` / `UiObject` (legacy), `Until` conditions, and `Configurator` global timeouts. Covers the singleton acquisition (`UiDevice.getInstance(InstrumentationRegistry.getInstrumentation())`), `pressBack/pressHome/pressRecentApps`, `device.findObject(By...)` cached-node refresh and `StaleObjectException` recovery, the `executeShellCommand` `@Discouraged` path vs `Context.startActivity` plus `<queries>`, and the full `By` factory catalog. Use when the user reports `StaleObjectException`, `Espresso InjectEventSecurityException`, `findObject returns null`, asks "how do I open Settings from a test", "toggle Wi-Fi", "dismiss notification shade", or "test that spans my app and another".

From the source SKILL.md

UiAutomator is the only AndroidX test framework that can drive UI across process boundaries — Settings, the dialer, system notifications, another app's activity. Espresso refuses (InjectEventSecurityException) when an event would cross to a foreign window. UiAutomator works against the platform AccessibilityNodeInfo tree, so it sees every window. This skill encodes the modern BySelector / UiObject2 API, the singleton acquisition, the StaleObjectException recovery pattern, and the cross-app launch path.

When to invoke it: Use when the user reports `StaleObjectException`, `Espresso InjectEventSecurityException`, `findObject returns null`, asks "how do I open Settings from a test", "toggle Wi-Fi", "dismiss notification shade", or "test that spans my app and another".
