desired_caps['deviceName'] = 'Android Emulator'
desired_caps['appPackage'] = 'com.android.calculator2'
desired_caps['appActivity'] = '.Calculator'
desired_caps['automationName'] = 'UiAutomator1'
driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
driver.quit()
报错解答：
1、Encountered internal error running command: Error: Unable to find an active device or emulator with OS 4.2. The following are available: emulator-5554 (4.4.2)
答：平台版本对不上，把desired_caps['platformVersion'] = '4.2'改成desired_caps['platformVersion'] = '4.4.2'
2、Encountered internal error running command: Error: UIAutomator2 is only supported since Android 5.0 (Lollipop). You could still use other supported backends in order to automate older Android versions.
答：Android版本低于5.0，所以需要设置#desired_caps['automationName'] = 'UiAutomator1'
