Working through the Notepad tutorial and have a question. When it builds the database with the fields rowid, title, and body - all three are private static final strings. But when a method like fetchnote() runs, it uses a long id to get the note. How does the method get that id if rowid is a string? I would like to modify the tutorial a ...

The typical amount of data I have to transfer is 5 to 15 nested objects wi...

However, all the solutions for decoding this JSON...
I'm working through the Notepad example, and I'm right at the end of v1. Everything works, I've even added a few small things by playing around with the layout and such.
