推荐答案

Google不允许使用WebView的默认实现.因此，您需要为WebView设置自定义User-Agent:

Google does not allow default implementations of WebView to be used. Therefore you need to set a custom User-Agent to your WebView:

webView.getSettings().setUserAgentString("YourAppName");

您可以使用任何字符串代替 YourAppName .

You can use any string instead of YourAppName.
