如何在不同的活动android中维护http post后的Cookie?
我在网上搜索了三天多,但没有找到任何解决办法。我正在进行http post登录,然后打开一个webview,它是我正在登录的webserver的链接。问题是webview没有显示经过身份验证的页面,请帮助我。 代码如下: `如何在不同的活动android中维护http post后的Cookie?,android,http,webview,http-post,session-cookies,Android,Http,Webview,Http Post,Session Cookies,我在网上搜索了三天多,但没有找到任何解决办法。我正在进行http post登录,然后打开一个webview,它是我正在登录的webserver的链接。问题是webview没有显示经过身份验证的页面,请帮助我。 代码如下: ` 公共类MainActivity扩展活动{ 私有字符串sessionokie; 私人厨师经理; 专用静态最终整数超时\u MS=3000; 私有网络视图; 专用静态最终字符串redirURL=”http://slateisb.nu.edu.pk/portal/relogin"

`我终于找到了解决这个问题的办法。 如果我使用异步任务调用http请求并将cookie存储到输出文件中。然后,我可以轻松地在我想要的任何活动中使用cookies。
也可以在不同的应用中使用这些cookies。对不起,我不明白。你能说得更具体些吗?这意味着将cookie存储到输出文件中是什么意思?
