图书描述

2012年6月1日
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. "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.

Full of typo's in the text and also in the coding.Around 15 found in the first 35 pages and didn't even read the blurb at the start. My main problem was that it didn't address how to input and out put the data to the android device it only shoed how to hardcode the information in and that is not going to be used often on most applications. If you already know how to write java to input your data to the database and how to display the data that you require to retrieve this will show you how to build a database and how to query it but not how to show that information on the device.

平均3.0 星 New to Android - old hand at C# and SQL 2013年8月14日
评论者 Gevalia - 已在美国亚马逊上发表
版本: Kindle电子书 已确认购买
This book covers files (internal and external storage), shared preferences, and SQL Lite. This books title should have been "Android Data Storage and Retrieval" because SQL Lite coverage is not a major aspect nor the other DB's that are briefly discussed. Coverage of SQL Lite for an Android beginner will get you there but it's light in details on performance beyond simply timing sql statements against the same functionality in Java. Why would you show me a few different ways of querying the DB and not show me metrics of each when you're showing me a metric of using aggregate functions in the sql statement versus doing it in Java code? Also the book states that foreign keys are not allowed but the sqlite.org web site says they are so this may be a version issue.

One MAJOR ISSUE I have with the kindle version is that there is no TOC on the left in the PC kindle version. I really hate this and there are many people that do as well. It seems to be a crap shoot with kindle books these days.

this book isn't written very well. the book seems like its just a compilation of someones notes of a bigger book. there are quite a few typos and errors in the code that, if you don't have a background in SQL maybe would be a issue. I purchased this book mostly for instruction on how to deal with blob objects (which ended up not being in the book) but also for the section on web scraping.. so hopefully there will be some good information when i get that far... over all not the best book from this publisher who normally is one of my first places to look for programming books.

平均2.0 星 VERY disappointing! 2012年8月3日
评论者 William E. Harris - 已在美国亚马逊上发表
版本: 平装 已确认购买
A number of *important* items are not covered at all in this book. Also, for items that are covered, they are not given a very in depth treatment. Some elements of the book are disconnected and are difficult to put together. At least one item was simply mentioned but not discussed. Some project samples downloaded from the publisher don't even work (they give an error message). After reading this book, I did not have a framework for a functioning database project. There are a lot of good free materials out there on this topic, so I would have expected a $40 book to have been much better. I could not recommend this book to anyone.

平均4.0 星 Android Database Programming (Impressions) 2012年8月31日
评论者 Carmichael - 已在美国亚马逊上发表
版本: 平装
TOC shows a solid and sensible progression but was suprised to see mention of the GAE and Servlets. I can see why this is at the end but could question whether a typical Android db user would find value in having 2 chapters on, what is essentially, non-Android databases - it's good, but beyond the impression the book title gives.

I'm an experienced Android developer. When I saw the SharedPrefences code right on page 2 of the first chapter I was suprised there had been no gentle lead up to the context (i.e. what an Activity is) or a stronger mention prior to this that this book is NOT for Android beginners. I went back and checked the "what you need for this book" and "who this book is for" sections, and yes, it's there, but a simple statement somewhere along these lines would prevent beginners getting frustrated and disappointed. However, for those who have done even light Android work before, the tone is spot on.

Android has evolved since its launch, and many of the old-school techniques are outdated. This book is bang up to date in that respect, showing the current best practice methods throughout. The writing style is very concise and readable whilst being brisk and to the point.
