Finding out all about Android Uri class - use and purpose

Question

Does anyone have some helpful links to find out about Android Uri's?

For example, you get a Uri back from a "take a picture" Intent. What does a URI look like and how do you use it. Why are they used instead of filenames or file handles?

The Dev documentation on the Uri class is practically worthless. http://developer.android.com/reference/android/net/Uri.html It is only clear if you already know exactly what it is, and how to use it.

Thanks for any links.

Hi,

I'd check out the content providers section

http://developer.android.com/guide/topics/providers/content-providers.html

It expalins URI's for the different content providers and how they work.
