Spawning off the "Dialog box without title" thread to discuss the pros and cons of storing Context as a member vs passing a parameter. Here's the last bit of the discussion from that thread:

I'm surprised you're seeing anything. It's not pointless, and please stop telling people that. :-) You just have to know when to use it. Use it when you need to store a context in an object that lives longer than an instance of an activity or service, but don't want to leak that activity or service. The application context is perfect for that.

If you need a Context, one is usually readily available wherever you happen to be and can be passed as a parameter. Do you have a good example of when storing a Context like this is a good idea? I'm just curious.
