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.
