So I ordered this having been impressed with the Pro series before. They cover in depth a lot of different subjects, from fragments, to visualizations, to background asynctasks, etc. However, they say explicitly that they don't deal with Loaders or really cursors. Now, cursors I can understand, but to not include Loaders in this book is a gross oversight. There are other things that this book leaves out, but the biggest component which is something, with today's data centric world, is really necessary. I would recommend waiting for a different book if you are looking for help in this area. However, this book does do well with a lot of other components so it is still worth while. That is why I gave it a 3 out of 5. It is good, but could be great.
