如何在多个活动之间共享相同的数据
问题描述：
我有一个登录会话ID，多个活动需要使用该ID.如何在多个活动之间共享此公共数据?目前，我正在Intent中传递数据，但它无法正常工作.对于某些活动，我传递了一些其他数据，但通用数据丢失了.
I have a login session ID which multiple activities need to use. How do I share this common data between multiple activities? Presently, I'm passing the data in the Intent but it is not working properly. For some activities, I pass some other data, and the common data is lost.

一种方法是扩展Application，然后在您的活动中调用getApplication. 此网站包含一些示例.
One way to do it is to extend Application, and then call getApplication in your activities. This site has some examples.
