Android Programming for Beginners

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.

Chapter 24. Adding a Database to Where It's Snap

In this chapter, we will be entirely focused on using all we know about fragments, interfaces, and SQLite in order to add significant functionality to Where it's Snap.

We will cover the following tasks:

  • Building a new class to represent a photo
  • Creating a DataManager class to handle our database, including a selection of helper methods to make the appropriate queries
  • Enabling the saving of photos into the database from the FragmentCapture class
  • Coding an interface to handle communications
  • Coding TagsFragment to show a list of tags and sending a tag to MainActivity when one is clicked
  • Coding TitlesFragment to show a list of titles either based upon a specific tag or the entirety of wis_tables_photos
  • Coding the MainActivity class to handle the communications of the fragments via the interface

As usual, the files for all of the above are in the download bundle in the Chapter 24/Where Its Snap 3 folder.
