Overview of this book

Android is the most popular OS in the world. There are millions of devices accessing tens of thousands of applications. It is many people's entry point into the world of technology; it is an operating system for everyone. Despite this, the entry-fee to actually make Android applications is usually a computer science degree, or five years’ worth of Java experience. Android Programming for Beginners will be your companion to create Android applications from scratch—whether you’re looking to start your programming career, make an application for work, be reintroduced to mobile development, or are just looking to program for fun. We will introduce you to all the fundamental concepts of programming in an Android context, from the Java basics to working with the Android API. All examples are created from within Android Studio, the official Android development environment that helps supercharge your application development process. After this crash-course, we’ll dive deeper into Android programming and you’ll learn how to create applications with a professional-standard UI through fragments, make location-aware apps with Google Maps integration, and store your user’s data with SQLite. In addition, you’ll see how to make your apps multilingual, capture images from a device’s camera, and work with graphics, sound, and animations too. By the end of this book, you’ll be ready to start building your own custom applications in Android and Java.

The SQL syntax primer

Before you learn how to use SQLite with Android, you first need to 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 an SQLite database directly, without any Java or Android classes, and then we can more easily understand what our Java code will doing later.

The SQLite example code

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

  • INSERT: This allows us to add data to the database
  • DELETE: This allows us to remove data from the database
  • SELECT: This allows us to read data from the database
  • WHERE: This allows us to specify the parts of the database that match a specific criteria that we want to insert, delete, or select data from
  • FROM: This is used to specify a table or column name in a database

Note

There are many more SQLite keywords than this, and for a full list of keywords, take a look at https://sqlite...
