mobium type
This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET
Type text into an element, after what it holds
Types into the element you name rather than whatever holds focus, so quotes,
spaces and non-ASCII arrive intact, after what the field already holds.
mobium fill replaces it instead. Not on Android's uiautomator dump driver,
which declines text entry rather than enter it wrong.
Usage
mobium type <@ref | locator> <text> [flags]
Examples
Type after what a field holds
mobium type testid=email "hello@example.com"
More, from mobium type --help
mobium type @e3 "hello@example.com"
mobium type testid=search "O'Brien & Sons"
mobium type @e3 "" # clear the field

type calls app_type; its arguments and what every client calls it are there.
