Asynchronous programming has acquired immense importance in Android programming, especially when we want to make use of the number of independent processing units (cores) available on the most recent Android devices.

To start with, you will get to know the details of the Android Process model and the Java low level concurrent framework delivered by Android SDK. Following this, we will guide you through the high-level Android-specific constructs available on the SDK: Handler, AsyncTask, and Loader. Next, we will guide you through the creation of IntentServices, Bound Services, and External Services, that can run in the background even when the user is not interacting with it. Next, you will discover the AlarmManager and the JobScheduler APIs, used to schedule and defer work without sacrificing the battery life. In a more advanced phase, you will create background tasks that are able to execute CPU-intensive tasks in the Java native layer, making use of the Android NDK. Finally, we will introduce you to RxJava, a popular asynchronous Java framework used to compose work in a concise and consistent way. Asynchronous Android Programming will help you to build well-behaved applications with smooth, responsive user interfaces that delight users with speedy results and data that’s always fresh.
