What do I do if I want to play music?
You can play some music in the background of your app using the
MediaPlayerclass. Here is some sample code to show how simple this can be:// Create a MediaPlayer object MediaPlayer mp = new MediaPlayer(); // Choose where to load the music from mp.setDataSource(musicFileToLoad); // Call the prepare method mp.prepare(); // Play some music mp.start();
Take a look at the official documentation for full details at http://developer.android.com/reference/android/media/MediaPlayer.html.
How about if I want to make an actual music playing app where the user can select music from their library to play.
This is also made easy for us by Android. On the Android Studio palette, you can drag a MediaController widget, which not only allows your user to control music playback but video as well. Find out how to use this widget on the Android developer site, http://developer.android.com/reference/android/widget/MediaController.html.

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.
