c# - 无法检测到 webview Appium

Question

我正在尝试通过 Appium 自动化混合 phonegap 应用程序。当这个应用程序在手机上运行时，我可以通过 Chrome 浏览器远程访问它。当我使用 Appium 时，它不显示 webview 上下文，只显示 native 上下文。有没有办法访问 webview 上下文，我做错了什么？

        var dirs = Directory.GetFiles("out", "*.apk");
        var app = Path.GetFullPath(dirs[0]);
        DesiredCapabilities cap = new DesiredCapabilities();
        cap.SetCapability("fastReset", "True");
        cap.SetCapability("platformName", "Android");
        cap.SetCapability("automationName", "Appium");
        cap.SetCapability("app", app);
        cap.SetCapability("deviceName", "emulator-5554");
        cap.SetCapability("autoGrantPermissions", "true");
        AppiumDriver<AppiumWebElement> driver1 = new AndroidDriver<AppiumWebElement>(new Uri("http://192.168.1.138:4723/wd/hub"),cap);
        Thread.Sleep(15000);
        var contexts = driver1.Contexts;
        foreach(string context in contexts)
        {
            if (context.Contains("WEBVIEW"))
            {
                driver1.Context = context;
                break;
            }
        }
        driver = driver1

同时添加一个日志文件:

找到了它没有检测到 webview 的原因。该应用程序使用 phonegap 构建并使用人行横道。这会导致 Appium(在正常情况下)找不到 webview 的问题。

Answer 1

尝试打印所有可用的上下文。有时拼写或大小写可能不同。以下是伪代码。

foreach(string context in contexts)
{
    print(context)
}

同时检查您是否在代码中启用了 webview 调试。

要做到这一点，请使用

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    WebView.setWebContentsDebuggingEnabled(true);
}
