Passing Future object between activities

Question

Coming from Java EE to an Android application (i'm not Guru in Java EE), For a fatest load of the application, we decided to process a files asynchronously, when the application starts, we launch some asynchronous channels to read the files, then we open the main activity, the idea is the user may not go directly to the use cases which need these files, but if he go it direclty and the asynchronous read wasn't terminated, he should wait a while(what the client wanted).

My question is how to passe the Future object between activities? my team agreed for using static methods or singletons, but i really don't love singleton because its an antipattern and i don't like static methods because they behave nearly like singleton.

Trying to use parceable or serializable, but future doesn't use implement anyone of it, i tried to use RoboGuice (its based on static fields but its busniss) but its a little buggy, how can i do it in android in pretty way, if there's another idea, i will be obliged to use singleton or static methods.

EventBus can be used to send objects from 1 place to another (eg asyncTask to Activity). It's great and easy to use, and it will accomplish what you're trying to do perfectly.

You can create your custom object classes to send between almost any 2 classes, Activities, Services, or whatever you with.
