Appium Appium 不懂就问，Appium 小白，在微信切换 webview 时遇到 Original error: unknown error: Failed to get PID for the following process: com.tencent.mm:tools 问题
已经在这个问题卡了很久了，望各位知道的大佬为小弟解惑
前置条件：
1.真机 OPPO R11st
2.安卓版本 7.1.1
3.真机 webview 66.0.3359.126（chrome 浏览器和微信内嵌 webview 同此版本）
4.appium 1.15.1
代码
public static void main(String[] args) throws Exception {
//创建配置对象
DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
desiredCapabilities.setCapability("deviceName","OPPO R11st");
//测试平台
desiredCapabilities.setCapability("platformName", "Android");
//安卓系统版本
desiredCapabilities.setCapability("paltformVersion", "7.1.1");
desiredCapabilities.setCapability("appPackage", "com.tencent.mm");
desiredCapabilities.setCapability("appActivity", ".ui.LauncherUI");
//不清除数据启动
desiredCapabilities.setCapability("noReset", "True");
desiredCapabilities.setCapability("recreateChromeDriverSessions","True");
//自动化引擎（解决输入框不能输入的问题）
desiredCapabilities.setCapability("automationName", "uiautomator2");
// 支持X5内核应用自动化配置
desiredCapabilities.setCapability("recreateChromeDriverSessions", true);
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("androidProcess", "com.tencent.mm:tools");
desiredCapabilities.setCapability(ChromeOptions.CAPABILITY, options);
desiredCapabilities.setCapability("browserName","");
//创建驱动
androidDriver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), desiredCapabilities);
//元素超时等待
androidDriver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
weChat();
//关闭驱动
androidDriver.quit();
}
public static void weChat() throws Exception {
Thread.sleep(5000);
androidDriver.findElementById("com.tencent.mm:id/r_").click();
androidDriver.findElementById("com.tencent.mm:id/m7").sendKeys("接口测试号");

Set<String> context = androidDriver.getContextHandles();
for(String contextname : context){
System.out.println(contextname);//打印
if(contextname.equals("WEBVIEW_com.tencent.mm:tools"))
androidDriver.context(contextname);
}
System.out.println(androidDriver.findElementsByXPath("//*").toString());
System.out.println("进来了。。。。。。");

// on Android O ps returns only user processes, so also try with -A flag.
chromedriver 使用的 ps 命令，不同版本 Android 系统执行结果不一样。
同样的错误信息，我这边问题解决了，发在这里看有没有帮助。
LZ 是做微信公众号的测试是吧？微信的版本是多少，已经开启 X5 的 debug 页面了是吧？
确定这些都没问题的话，继续往下。最后发现是 chromedriver 版本问题导致的，折腾了一周多....
关键字：不要相信 Android 系统显示的 webview 版本，通过 chrome://inspect/ 来查看设备的 chrome 版本
确定后到https://github.com/appium/appium/blob/master/docs/en/writing-running-appium/web/chromedriver.md 查看对应的 chromedriver 版本，下一个就好了
升级 webview 版本吧，这个太老了，查下安装得 chromedriver 版本，然后升级下手机端得 webview 版本
