PhoneGap 2.x Mobile Application Development Hotshot, and write my thoughts on it.
As the topic is in my interest sphere and I was having a long flight ahead, I decided to use that time to read it. So I read the book on my iPad in about 9 hours, but didn't try the code the comes with the book yet.
The book is mostly build of examples, which is a great way to see the potential of the tool. The author starts with giving a brief overview what PhoneGap is and where it fits in. It also walks you through how to prepare your environment to run the examples. Next it's all examples... The first chapter talks about how to create multilingual applications and sets the foundation for the other chapters. I found it interesting to see the author is using the YASMF framework (instead of for example JQuery Mobile).
In the second chapter you basically build a basic twitter application which also allows you to share the information. To do the sharing she used ShareKit, a very nice open source project.
In the following chapters she builds applications around the PhoneGap's File APIs, geolocation features together with Google Maps, recording and playing of audio, using the camera to store pictures and video, all very nice examples.
Chapter 8 is interesting as it builds a game! Behind the scenes it's using the HTML5 canvas, multi-touch gestures and the accelerometer. It's also reusing some of the things you learned in previous chapters like the file api, but it expands now to use localStorage.
The final two chapters are about expanding PhoneGap with native functions from the device and supporting bigger mobile devices like the iPad.
As you can see, a lot of ground is covered, with all excellent and useful examples!
