Android Web应用安装横幅未显示

我有一个网站（），我相信它符合web应用程序安装横幅的所有标准，但横幅没有显示出来。有人能帮我找出原因吗？（我试过带国旗和不带国旗chrome://flags/#bypass-应用程序横幅参与检查）

我正在使用Chrome进行Android稳定v44。*

我已经解决了这个问题。此时，“start_url”属性似乎是显示横幅所必需的。我添加了“开始url”：“/index.html”以显示横幅。

真的吗？我想如果你没有“开始url”，那么当前页面将显示横幅…它不是显示横幅的页面的“开始url”，而是“已安装”Web应用程序通过其图标启动时开始的起始url。
