如何在 webview 和 chrome 中同步 cookie android

Question

我已经搜索过这个，但直到现在还没有在 stackoverflow 中找到答案。 我的项目是创建 android webview 应用程序显示网站的移动版本。 我知道网站在 Chrome 浏览器中运行时无法检测到安装在设备上的应用程序以确保安全。

所以我用附加应用程序的名称更改了 android 应用程序的用户代理.. 然后每次用户使用该应用程序时，网站都会检测到 web 正在 webview 中运行，然后在设备中写入厨师“Appname”。

如果用户使用 chrome 浏览网站，则会从那里找到该 cookie，如果未找到该 cookie，则会显示一些链接帮助用户安装应用程序。

问题是我的应用和 chrome 之间的 sysn cookie 看起来不起作用。

以下是我的activity.java 感谢您的帮助！
