        # starting session based on set capabilities
        self.driver = webdriver.Remote(SERVER_URL, options=options)
        self.driver.start_activity(desiredCapabilities["appium:appPackage"],desiredCapabilities["appium:instrumentApp"])

I am getting AttributeError: 'WebDriver' object has no attribute 'start_activity'

But according to the docs this is supported.

Please help.

this document is out of date. Use https://github.com/appium/appium-uiautomator2-driver#mobile-startactivity instead

@mykola-mokhnach I tried:

self.driver.startActivity(desiredCapabilities["appium:appPackage"],desiredCapabilities["appium:instrumentApp"])

But i am getting AttributeError: 'WebDriver' object has no attribute 'startActivity'

My UiAutomator2 driver version is 2.25.1

Any update on this? I am also getting same error

Are you moving from Python Client 2 to 3? If so this will help:

I am new to appium and not sure how to use this mobile:startActivity.

My previous code was with python was like below

if secure_activity:
if secure_activity:
                        self._driver.start_activity(
                            app_package,
                            app_activity,
                            app_wait_activity=secure_activity
                        )
                    else:
                        self._driver.start_activity(app_package, app_activity)
                    logger.debug("Appium Server Re-connection Time: %s", time.time()-start_time)

I’m always a big fan of looking at the tests in the source code to see how some code snippet is used. Here are the activities_tests.py:
