First thing first...I read it...but didn't actually spend too much time doing all the projects, so I'm for sure will read it again -:D
So...is this book good or bad? I will say...it's really good!
For me...the best way to learn a new programming language or tool...is by actually build stuff with it...and this book is full of practical projects that will dive you deep in the PhoneGap development.
The book include projects that deal with Twitter, Camera, Storage and even GeoLocation...also...it includes a small game! How awesome is that?! Really awesome -:)
The projects are easy to follow, but of course...they are not simple...they are complex and that adds more flavor to them...you really need to be focused on what you're doing to get the full grasp of it...but again...by doing it yourself, you will learn it more quickly and will not forget it anytime soon...
I want to show you a couple of images of two of the projects included in the book...so you can have an idea of what you're going to build...
BTW...even when I'm posting only Android based images...the book focuses on both IOS and Android.
If you have never used PhoneGap before...or you're a newbie with little experience like me...then this book really is for you...happy coding!
