UiAutomator UiAutomator2 测试 H5 页面，切换 webview 后报没有找到对应的 ChromeDriver 版本
测试手机：
华为/vivo手机，webView版本是78.0的（其他手机不会出现下面的问题，如：小米、Honor）
前置描述
- APP 已经开启 Debug 模式（用 appium 操作是没问题的）
- 用 Chome 浏览器查看'chrome://inspect/#devices', 版本如下
- 已经准备了对应的 ChomeDriver 版本
现象
- chromedriver 实例化后，发现会拉起本地 Chrome 浏览器
- 接着就报 ChromeDriver 版本不对

现象再复述一下：
对应 chromedriver 驱动，开启 chrome 远程端口，发现会拉起本地 Chrome 浏览器（部分机型会出现该问题）
经过测试，如下：
- 使用小米 CC9，webview 版本 83，会出现该问题
- 使用华为手机，自带的 webview，会出现该问题
- 使用小米 6，webview 版本 74，不会出现问题
- 使用三星 s8，webview 版本 73，不会出现该问题
总结：
不管什么手机的 webview，直接用 72 版本的 chromedriver 驱动（这个驱动版本稳定）就可以用，已经在以上 4 部手机实践过，没问题。

您好，
- 我是测试 APP 里面的 webview 页面
- 我用 appium 操作 webview（就如您所说的 context），是没问题的
- 现在用上述的代码，我在小米及 Honor 是可以跑成功的，但是华为跟 vivo 就不行
- 我是参考这篇文章的，ATX ATX-uiautomator2 app 原生 + webview 的实际操作记录 (安卓) https://testerhome.com/topics/15998
- 按照您的意思是在 lunch_driver 时就应该传入配置信息吗？
对

额，你这个回答和我的问题对不上吧。
另外，官方文档里 options 不是你代码里这个写法传进去的，而是下面这样：
from selenium import webdriver
options = webdriver.ChromeOptions()
options.add_experimental_option('androidPackage', 'com.android.chrome')
driver = webdriver.Chrome('./chromedriver', options=options)
driver.get('https://google.com')
driver.quit()
初始化启动 chromedriver 的时候就传入 options 了。
官方文档地址：https://chromedriver.chromium.org/getting-started/getting-started---android
你确定过你现在这种写法（命令行调起 chromedriver 文件，然后用 webdriver.Remote 连上 chromedriver 服务并传入 capabilities ）是可用的吗？
对

@codeskyblue , 不好意思，重新发一下代码
这个是 ChromeDriver 类文件，跟您写的应该是一样的
from __future__ import absolute_import

self._port = port
self.log = log
self.common = common
self.phone_name = phone_name
def _launch_webdriver(self):
self.log.info("start chromedriver instance")
chrome_driver_path = self.common.select_chromedriver(self.phone_name)
p = subprocess.Popen([chrome_driver_path, '--port=' + str(self._port)])
try:
p.wait(timeout=2.0)
return False

app = self._u2.app_current()
print(app)
capabilities = {

print(capabilities)
# self.kill_chromedriver()
time.sleep(2)
self._launch_webdriver()
dr = webdriver.Remote('http://localhost:%d' % self._port, capabilities)
# always quit driver when done
atexit.register(dr.quit)
return dr
实际调用的代码如下：
driver = ChromeDriver(u2, log, common, phone_name).driver()
# 通过搜索来选择设备
search_input = common.wait_element(driver, (By.XPATH, Add_Device_Locator.search_classname_locator))
chromedriver 实例化后，发现会拉起本地 Chrome 浏览器
这段话很奇怪，你测试的是手机里的浏览器打开 web 页面，还是你的 app 内置 webview 里的 web 页面？如果是后者，我理解只需要实例化 appium driver，用 driver 内部切换 context 的方法来切换到 webview 就好（appium 有内置 chromedriver ），不需要实例化 chromedriver 。
最好还是直接贴一下你的脚本代码吧。
自己顶一下，没人帮忙看下吗
@codeskyblue 可以帮忙看下嘛？
