我在 UI Automator Viewer 里面获取了 resource id，但是运行时还是报错找不到该元素，为什么呢？我是真机测试
#! /usr/bin/env python
#coding=utf-8

from selenium import webdriver
from lib2to3.pgen2.driver import Driver
from lib2to3.tests.support import driver

PATH=lambda p:os.path.abspath(os.path.join(os.path.dirname(file),p))
global driver

desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['platformVersion'] = '4.2'
desired_caps['deviceName'] = 'Lenovo P1c72'
desired_caps['app'] = PATH('C:\Users\LENOVO\Desktop\StarZone_V2.0.0.apk')

driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)

driver.find_element_by_id("com.xiangchao.starspace:id/skip").click()

报错：
selenium.common.exceptions.NoSuchElementException: Message: An element could not be located on the page using the given search parameters.
