Content Providers

Looking at the Android API Guide, content providers appears to be the remaining core components that I have not touched upon: http://developer.android.com/guide/topics/providers/content-providers.html.

Turns out, however, that is a specialty case that we are unlikely to use very often.

You don't need to develop your own provider if you don't intend to share your data with other applications.

So, will pass on them for now.
