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.
平均3.0 星 not every book can be the best, but this one is ok... 2014年11月23日

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.

平均4.0 星 Solid First Impressions 2012年9月1日
评论者 Rick Boyer - 已在美国亚马逊上发表
版本: 平装
I received this eBook for the "One Day Review Challenge", so I haven't had time to read the entire book yet.

The book states the target audience as "experienced developers new to mobile database development". Thankfully, there's no "Hello World" here but instead gets right in to the details of data storage. It's not just about databases either, topics range from SharedPreferences, to file storage and SQLite.

In contrast, one book I recently read presented the basics of SQLite in one (long) chapter, whereas, this is an entire book devoted to the same concepts. I got the basics there, but I'm happy to get in to more detail with this book. As mentioned in the Table of Contents, this book even covers working with external (web) resources.
One aspect of this book I really like is the authors attempt to explain the use of the concepts presented. Various chapters have "Common Use" or "Putting it together" sections to give ideas on the best use for the ideas presented, not just the dry details of how to do it. I wish more authors did this.

Overall, the book has a nice clean layout and I haven't seen any glaring typos. If you're looking for the details of data storage, not limited to SQLite, on the Android, I'd say it's worth picking up.

Update: After finishing the book, I can still give a 4/5 stars. As mentioned before, it's not limited to SQLite so it gives a good overview of options available on Android. I recommend this book for developers new to Android.
