I'm developing an Android app which will be compatible with API 14 (Ice Cream Sandwich). I've found the class `HttpResponseCache` which can be used to cache HTTP requests. I want to integrate the cache with my HTTP request code (a common class with a bunch of `public static` methods).  

The `HttpResponseCache` documentation explains that the cache has to be installed and closed on every Activity or Service where used. I want the cache to be always enabled on my application but I don't want to remember to install the cache and close it on every new activity I develop.

Is there a pattern to achieve this?
