Do I really need Content Provider in my application

I am creating app that should have offline mode, so previously downloaded data should stored somewhere, the most common way is to store data in SQLite database.

Mostly SQLite database is used with Content Provider in android. I have clear understanding what is the purpose of content provider (to share data between different apps), but in my case application will never need to share the data with other apps in the system.

Content provider has the similar interface as HTTP request (GET,POST,PUT,DELETE).
My idea is to create facade class which can be asked like this getAllLatestNews(); firstly it will try to get latest data from the internet, if it fails data from database will be used and if request was successful it also will save retrieved data to the database. This class will be facade for separating different layers of application (not to make requests from activities directly).

But now I am a little bit puzzled deciding whenever I need Content Provider or not. I can use SQLiteOpenHelper classes to retrieve and save data to the database or even use ORM library to do this.
At first I wanted to implement REST API Pattern B by Virgil Dobjanschi. But now I am not sure about this, maybe it would be better to create facade for Robospice(in my case, network request in the service) requests and do persistence there ?

Please share you thoughts about this topic, I would be grateful for any help.
