Overview of this book

Do you want to make a career in programming but don’t know where to start? Do you have a great idea for an app but don't know how to make it a reality? Or are you worried that you’ll have to learn Java programming to become an Android developer? Look no further! This new and expanded third edition of Android Programming for Beginners will be your guide to creating Android applications from scratch. The book starts by introducing you to all the fundamental concepts of programming in an Android context, from the basics of Java to working with the Android API. You’ll learn with the help of examples that use up-to-date API classes and are created within Android Studio, the official Android development environment that helps supercharge your mobile application development process. After a crash course on the key programming concepts, you’ll explore Android programming and get to grips with creating applications with a professional-standard UI using fragments and storing user data with SQLite. This Android Java book also shows you how you can make your apps multilingual, draw on the screen with a finger, and work with graphics, sound, and animations. By the end of this Android programming book, you'll be ready to start building your own custom applications in Android and Java.

SQL syntax primer

Before we can learn how to use SQLite with Android, we need to first learn the basics of how to use SQLite in general, in a platform-neutral context.

Let's look at some example SQL code that could be used on a SQLite database directly, without any Java or Android classes; then we can more easily understand what our Java code is doing later on.

SQLite example code

SQL has keywords, much like Java, that cause things to happen. Here is a flavor of some of the SQL keywords we will soon be using:

  • INSERT: Allows us to add data to the database
  • DELETE: Allows us to remove data from the database
  • SELECT: Allows us to read data from the database
  • WHERE: Allows us to specify parts of the database, matching specific criteria, that we want to use INSERT, DELETE, or SELECT on
  • FROM: Used to specify a table or column name in a database

    Note

    There are many more SQLite keywords than this; for a full list of types, take a look at this link: https:...
