Error when using driver.set_value or element.set_value


I’m trying to set the text input value in a TextView UI element of my Android app. I used the following code:

AppTextView = driver.find_elements_by_class_name(“android.widget.TextView”)
driver.set_value(AppTextView[3], ‘testing’)

The error I get is the following:

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: ‘Not yet implemented. Please help us:

Is it possible I need newer version of Appium or/and Python client. I currently have Appium and Python client 0.9.
