I am lost. I an reading along and see "Skeleton" code snippets and suddenly there is a snippet from MyHoardContentProvider or MyHoardDatabase. These classes are only in the snippet project "PA4AD_Ch08_ContentProviders". There is no complete project, and a search of the entire book shows that examples for it are only in chapter 8.

There is no explanation of what this MyHoard project is, what it does, or what the database structure is. So, I am trying to understand what this implementation specific example does and coming up empty. Or why the book goes from showing a skeleton snippet of one method and then a method from these classes.

Oh yea. There is a class HoardDBOpenHelper that is only mentioned in the book. No code snippet for it. WTF?

Content providers can be a pretty complex subject to explain. I can't speak for why Reto chose this Horde example, but it might have been because he thought it was better and/or easier to cover the subject than doing a full project.

The "Creating a To-Do List Database and Content Provider" on page 283 might be better for you to look at.

As for the HoardDBOpenHelper snippet, I believe you'll find it in MyHoardDatabase.java

Thanks. I too found the HoardDBOpenHelper as an inner class of both of the other two files.

It would appear that Reto has abandoned supporting his book over a year ago. As such I have decided to abandon the book and find other sources.
