First and foremost, Kyle Mew explores Android development using Android Studio by introducing basic and broad tooling concepts better than you may find elsewhere. I wish I could find such work 2 years ago. The reason I'm giving 3 stars is that, I see his work as concise but narrowed. Meaning that you may find everything you may need to know in order to be ok using Android Studio but we’ll feel the need to keep going elsewhere. You’re not mastering anything. This book is about a tool, in order to be a rich asset, more arguments could be used.
The command-line tool was joke. He introduced the argument to setup external storages but wouldn’t explain how I could run the command. Also, the project dependences could have more details about the scope dependence and dependency types. This is classic error from books like this but I don’t blame the author. Packtpub team has a nice platform to read because its html style, illustration and somehow the interactivity, but the team didn’t make a proper revision of the book itself.
