client.session() hands you inside a
session. It’s the object every action runs on: finding, tapping, typing,
swiping, and reading the screen. Methods that point at something return a
Locator; reading the whole screen returns a
Screen.
The detailed signatures below use Python. The Go SDK exposes the same DCP
surface with Go naming and explicit duration arguments; see the method map at
the end. Live phone actions are not REST operations.
Connection and capabilities
driver.handshake()
Return the executor’s protocol version, device descriptor, domains, and exact
capability set. Gate optional behavior on these advertised capabilities.
HandshakeResult.
driver.device_info()
Return the phone’s static DCP descriptor.
DeviceInfo.
driver.close()
Close the underlying control transport. client.session() calls this and
deallocates its phone automatically when the context exits.
Locating
driver.get_by_text()
Point at something by its visible text, read by OCR. Nothing is sent until you
call an action on the result.
Returns
Locator.
driver.locator()
Point at something by describing it in plain English, for when there’s no text
to match (an icon, an image). A description runs a
vision-language model, so it costs more than text.
Returns
Locator.
Tapping
driver.tap()
Tap an exact point on the screen. To tap something you located, call
locator.tap() instead.
None. coords is a {"x": int, "y": int} dict.
driver.long_press()
Press and hold an exact point, for example to open a context menu. To hold a
located target, read its position with
locator.bounding_box().
Returns
None.
Typing
driver.type_text()
Type into the field that’s already selected. To tap a field and type in one call,
use locator.fill(). To press Enter
(submit / search), use driver.key_press().
None.
Swiping
driver.swipe()
Swipe between two points. This is also how you scroll: swipe up (end higher
than start) to move down a list. To drag one located target to another, see
Swipe.
Returns
None.
Buttons
driver.key_press()
Press a named key. Key.ENTER submits a form or fires the
on-screen keyboard’s Go / Search.
None. key is a string; see Key for the constants.
driver.press()
Press a named key against whatever has focus, through the same path as a
locator action. To focus a specific target first, use
locator.press().
LocatorResult with no bounds,
since nothing was located.
Reading the screen
driver.observe()
Read everything on the screen at once, all text and icons, as a queryable
snapshot you can search without going back to the phone.
Returns
Screen.
driver.screenshot()
Take a picture of the screen as PNG image data, to save, log, or debug a run.
bytes: raw PNG data.
Go method map
Go constructs a driver withmobile.ConnectRemote(controlURL, options...).
Use mobile.WithDefaultOCREngine, mobile.WithDefaultModel, and
mobile.WithOpenTimeout for connection-wide defaults. Observe, Handshake,
and DeviceInfo take mobile.WithOCREngine. Locators take the options listed
in the Locator reference.
Go requires gesture duration arguments where Python supplies defaults.
