I'm pretty much always going with a constructor parameter approach. I pass it in the instantiation and keep a private reference in the instantiated class.

You have to think about one important thing. If the class you pass the Context will exist longer than the Activity instantiating it then you should use the application context. If that class is doing UI stuff you will need an activity context.

Make sure that the class you are passing an activity context to won't last longer than the Activity or you'll leak the entire activity.

If you don't do UI stuff then go with the application context.
