                      Jason Wei

                      Jason Wei graduated from Stanford University in 2011 with a B.S. in Mathematical Computational Science, a minor in Statistics, and an M.S. in Management Science & Engineering with a concentration in Machine Learning. He spent his first two years in college with startups in Silicon Valley, and it was at his second startup (BillShrink, Inc) that he was introduced to Android. Since then he has developed a handful of applications ranging from silly screen prank applications to serious financial pricing and modeling tools. He also enjoys working with APIs and competing in application development contests – winning a number of contests hosted by companies like Google, MyGengo, IndexTank, amongst others. In addition to developing applications, Jason enjoys writing Android tutorials and sharing his own development experiences on his blog (thinkandroid.wordpress.com), and it was through his blog that he was first invited to be a technical reviewer for the book Learning Android Game Programming. Jason is currently working as a quantitative trader in New York.

                      The second bullet for the mode argument values should be "MODE_WORLD_WRITABLE" and not "MODE_WORD_WRITABLE". It is WOR[L]D and not WORD

                      In Detail

                      We live in an increasingly data-centric and data-driven world. On top of that we live in a very mobile-centric world with the rise of Android smart phones and tablet devices and the surge in demand for the Android platform. Along with the demand for more data, there is a demand for efficient, "snappy" applications, and so developers need to have a strong understanding of when different data storage methods are appropriate and when they are not.

                      Mastering how to use these two fields to successfully create a powerful application will help you boost your knowledge and skills in this area.

                      "Android Database Programming" is designed to help developers create and design data-centric mobile applications on Google’s Android platform. As the world goes increasingly mobile and as consumers’ demand for data-centric applications rises, knowing how to combine the two effectively will become an increasingly important asset to have as a developer. The book starts by looking at the various local data storage methods on Android, and finishes off by examining external databases and ways you can utilize them from within an Android application.

                      This book starts by looking at local data storage methods, focusing on writing SQLite databases for your application and also looking at ways to bind these databases to the user interface. The book, through its practical approach, strives to teach you by examples. Each chapter focuses on flushing out high level design concepts, before drilling down into different code examples. 

                      As you continue you will look at external databases, primarily Google’s App Engine platform, and pull things together by helping you understand how you can request, cache, and display this data. The book then teaches the ways and techniques to utilize such external databases from within your application.

                       

                      Approach

                      This book is a practical tutorial approaching the topic with clear instructions and examples. With easy to understand examples and scenarios you can apply almost anywhere, this book walks you through both local and external data storage methods for the Android platform.

                      Who this book is for

                      "Android Database Programming" targets developers who are experienced with databases and other back-end design concepts, but who may want to see these concepts applied to mobile applications. Developers who are experienced with mobile applications and/or the Android platform, but who may not be as familiar with back-end systems and designing/implementing database schemas will find this tutorial equally useful.

                      Even if you are already experienced with both Android programming and database implementation, but want to further solidify concepts and see a broader scope of data storage methods on Android, this book is your perfect companion.
