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.

Preparing to publish

You probably don't want to upload any of the apps from this book, so the first step is to develop an app that you want to publish.

Head over to https://play.google.com/apps/publish/ and follow the instructions to get a Google Play developer account. This was $25 at the time of writing and is a one-time charge with no limit on the number of apps you can publish.

Creating an app icon

Exactly how to design an icon is beyond the remit of this book. But, simply put, you need to create a nice image for each of the Android screen density categorizations.

This is easier than it sounds. Design one nice app icon in your favorite drawing program and save it as a .png file. Then, visit http://romannurik.github.io/AndroidAssetStudio/icons-launcher.html. This will turn your single icon into a complete set of icons for every single screen density.
