List connected Android devices and their state (device/unauthorized/offline).

Launch an app by its Android package name (e.g. 'life.overture.beam').

Force-stop an app by package name.

Return a compact text list of the on-screen elements (label, tap point, id). Cheaper than a screenshot; use this to choose what to tap.

Capture the current screen as a PNG so you can visually inspect it.

Tap at absolute screen coordinates.

Tap the first element whose text/description contains text (set exact=True to match the whole label).

Type text into the currently focused field.

Press a key: back, home, enter, tab, delete, menu, app_switch, or a raw KEYCODE_*.

Swipe up, down, left, or right from the center of the screen.

Wait until an element containing text appears (up to timeout seconds).

Assert that an element containing text is on screen. Raises if absent.

Return the device screen size as 'WIDTHxHEIGHT'.
