解决办法：修改Appium安装目录下的文件，例如：

D:\Program Files\Appium\node_modules\appium\lib\devices\android\android-hybrid.js

找到androidHybrid.startChromedriverProxy 函数，注释掉相关内容。

 

 

问题原因：

Appium第一次切换到Html页面时，会新生成一个Chromedriver；当第二次切换到Html时，会使用已经存在的Chromedriver。但其实在我们的应用里面每次打开一个Activity时一般都是会重新创建一个WebChromeClient，所以这里就把它改成无论如何都生成一个新的Chromedriver。
