launchApp

Launch or activate an app on the device. If no bundleId (iOS) or appId (Android) is provided, the command will automatically detect and activate the currently active app.

Note: Falls back to the deprecated Appium 2 protocol endpoint if the driver does not support the mobile: execute method.

Usage

browser.launchApp({ bundleId, arguments, environment, appId })

options.arguments optional	string, string[]	Command line arguments to pass to the app on launch. iOS-ONLY
options.environment optional	object	Environment variables to set when launching the app (key-value pairs). iOS-ONLY
