How many content providers can we implement in one application?

I read the Android dev manual and notice that we can implement different classes for the content provider. So,

  • Does one Android app have multiple content providers or just one content provider?
  • How to implement different classes of content provider?

Here is what I read from the developer guide:

You are implementing a provider as one or more classes in an Android application

But having too many content providers can really confuse you and is not required. The only scenario I see for multiple content providers is that you have several databases in your application and you want to share all these databases with external applications. Where you can use a separate content provider for each database to share it with the outside world.

Hope this helps.
