The Application object 博客分类： android ApplicationAndroid

An Application object has a well-defined lifecycle and can be used as a data structure for holding an application's global state.It's created when the process for your application is created, and it isn't bound

to a particular Activity or Service. This means it's a great and extemely simple way to hold onto and share

nontrivial and nonpersistent data between activities and services within your applications.
