appium+ 真机:华为 安卓8.0系统 ;Webview version: 'Chrome/69.0.3497.100'
报错信息一直是:no page found 或者 urllib3.exceptions.ProtocolError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response'))

安卓上,Webview需要做如下设置,才可以。

WebView.setWebContentsDebuggingEnabled(true);

让开发打的debug包,chrome remote debug 可以看到HTML页面结构;
我这边有多进程同一个页面,不知道是否有关系
WEBVIEW_tv.danmaku.bili:web 会提示Chrome version on the device: Chrome/69.0.3497.100 ;
WEBVIEW_tv.danmaku.bili 提示 Webview version: 'Chrome/66.0.3359.126'
chrome debug 打开时,会显示webview in tv.danmaku.bili(66.0.3359.126)或者webview in tv.danmaku.bili(69.0.3497.100)
切换到固定的一个webview: self.driver.switch_to.context('WEBVIEW_tv.danmaku.bili:web') 目前应该切换成功了,现在报打不开这个页面
unknown error: unable to discover open pages

我现在跟你报一样的错误:unknown error: unable to discover open pages,Webview版本也是66.0.3359.126,请问你解决了吗?
