Navigate back and discard message

What we do next is to navigate back and discard the changes we made to the message.

Firstly, we just use the appium method driver.back to navigate back, same as iOS.

And we can also use value to locate the discard "OK" button.

discard = button 'OK'
discard.click

And we can get this screen in app:

Now the script should look like:

require 'rubygems'
require 'appium_lib'

caps = { caps: { platformName: 'Android', appActivity: 'ui.ConversationList', appPackage: 'com.android.mms' }, appium_lib: { sauce_username: nil, sauce_access_key: nil } }
driver = Appium::Driver.new(caps)
Appium.promote_appium_methods self.class
driver.start_driver.manage.timeouts.implicit_wait = 20 # seconds

mms = find_element id: 'com.android.mms:id/action_compose_new'
mms.click
to = find 'To'
to.send_keys 'no one'
message = textfield 'Type message'
message.send_keys 'empty'
driver.back
discard = button 'OK'
discard.click
