做完下列步骤后,模拟器无任何反应,请问下,是哪里没正确么 ?

1 搭建好环境
2 创建模拟器 test_avd,并启动
3 启动 appium
4 python 脚本为:

#coding=utf-8
from appium import webdriver
from time import sleep

desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['platformVersion'] = '6.0'
desired_caps['deviceName'] = 'Android Emulator'

desired_caps['app'] = 'Calculator.apk'
desired_caps['appPackage'] = 'com.android.calculator2'
desired_caps['appActivity'] = '.Calculator'

driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
sleep(3)
driver.find_element_by_id('com.android.calculator2:id/digit_5').click()

5 运行该 python 脚本
6 appium 输出:
