J2ME & Gaming by Jason Lam
   
  Description
  This book is about programming with J2ME on wireless devices with focus on developing games. It is assumed you have some knowledge and programming experience with J2ME and J2SE. The book does not go into detail on topics like how to make high level GUI menu but does demonstrate what a game menu might look like. Nor will it explain in detail how to use the Record Management System (RMS), but will go over topics that use RMS such as high score and game settings. As well a knowledge and experience with threading will be an asset before proceeding with game development. The book will go over in detail the new game classes that are now included in the MIDP 2.0.

The book also serves as quick reference for Java programmers who are interested in mobile game development. As well, to provide good introduction for experience game developers who developed games in other languages/platforms and are now interested in using J2ME to develop games.

Book FAQ
  Q: How can you say thank you!
  A: Just spread the word about my book and other tutorials.
   
   
  Q: Why is it Free?
 

A; Originally I wanted to find a publisher, but due to unknown time schedule I've decided to release it for free.
   
  Q: Are you not concerned someone else will make money off your hard work?
  A: Well with reference to my first book, J2ME & Gaming, other then the hard work of putting the book together there really isn't anything in the book that is special. Anyone with game experience knows there are dozens if not more then hundred different factors that contribute to making a successful game aside from the technology and code itself. Such things as demographics, gameplay, game graphics, community, persistant data, interface design, user experience, game narrative, character development.... etc The objective of this book is the process of learning how to implement a game not how to make a successful game. There is a difference and one should not confuse the two.
   
  Q: Why Can't I Print it?
  A: To help save the trees I've disabled the print function on the PDFs
   
  Q: Can We Publish Your Book(s)?
  A: Yes, please contact me if you are interested in publishing it. However, please understand the entire book is currently released under the GPL. Any publication will need to adhere to the terms of use as stated in the GPL..

  Description from the O'Reilly site:

The BlackBerry has become an invaluable tool for those of us who need to stay connected and in the loop. But most people take advantage of only a few features that this marvelous communications device offers. What if you could do much more with your BlackBerry than just web surfing and email?

BlackBerry Hacks will enhance your mobile computing with great tips and tricks. You'll learn that the BlackBerry is capable of things you never thought possible, and you'll learn how to make it an even better email and web workhorse:

  • Get the most out of the built-in applications
  • Take control of email with filters, searches, and more
  • Rev up your mobile gaming--whether you're an arcade addict or poker pro
  • Browse the web, chat over IM, and keep up with news and weblogs
  • Work with office documents, spell check your messages, and send faxes
  • Become more secure, lock down your BlackBerry and stash secure information somewhere safe
  • Manage and monitor the BlackBerry Enterprise Server (BES) and Mobile Data System (MDS)
  • Create web sites that look great on a BlackBerry
  • Develop and deploy BlackBerry applications

Whether you need to schedule a meeting from a trade show floor, confirm your child's next play date at the park, or just find the show times and secure movie tickets while at dinner, this book helps you use the remarkable BlackBerry to stay in touch and in-the-know--no matter where you are or where you go.
