Asynchronous Android Programming, 2nd Edition

Book Description

About This Book

• Construct scalable and performant applications to take advantage of multi-thread asynchronous techniques
• Explore the high-level Android asynchronous constructs available on the Android SDK
• Choose the most appropriate asynchronous technique to implement your next outstanding feature

Who This Book Is For

This book is for Android developers who want to learn how to build multithreaded and reliable Android applications using high-level and advanced asynchronous techniques and concepts.

What You Will Learn

• Get familiar with the Android process model and low-level concurrent and multithread constructs available on the Android SDK
• Use AsyncTask to load data in the background, delivering progress results in the meantime
• Enhance UI performance and responsiveness by sending work to a service running in the background
• Defer, schedule, and batch work on the Android system without compromising the battery life and user experience
• Use the JNI interface to execute concurrent work on native layer
• Pull and push data from your network servers using the Google GCM platform
• Create and compose tasks with RxJava to execute complex asynchronous work in a predictable way
• Get accustomed to the use of the Android Loader construct to deliver up-to-date results

In Detail

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, we will discuss the details of the Android process model and the Java low-level concurrent framework, delivered by the Android SDK. Next, we will discuss the creation of IntentServices, bound services, and external services, which can run in the background even when the user is not interacting with them. In a more advanced phase, you will create background tasks that are able to execute CPU-intensive tasks in native code–making use of the Android NDK.

You will be then guided through the process of interacting with remote services asynchronously using the HTTP protocol or Google GCM Platform. Finally, we will introduce RxJava, a popular asynchronous Java framework used to compose work in a concise and reactive way.

关于本书

• 构建可伸缩且高性能的应用程序，以利用多线程异步技术
• 探索Android SDK上可用的高级Android异步构造
• Choose the most appropriate asynchronous technique to implement your next outstanding feature

这本书是为谁写的

这本书是为想要学习如何使用高级和高级的异步技术和概念构建多线程和可靠的Android应用程序的Android开发人员编写的。

你将学到什么

• 熟悉Android进程模型以及Android SDK上提供的低级并发和多线程结构
• 使用AsyncTask在后台加载数据，同时提供进度结果
• 通过将工作发送到在后台运行的服务来增强用户界面性能和响应能力
• 在不影响电池寿命和用户体验的情况下，在Android系统上延迟、调度和批处理工作
• Use the JNI interface to execute concurrent work on native layer
• 使用Google GCM平台从您的网络服务器拉取和推送数据
• 使用RxJava创建和组成任务，以可预测的方式执行复杂的异步工作
• 习惯使用Android Loader构造来提供最新的结果

In Detail

异步编程已经在Android编程中获得了巨大的重要性，特别是当我们想要利用最新Android设备上可用的独立处理单元(内核)的数量时。首先，我们将讨论Android进程模型和由Android SDK提供的Java低级并发框架的细节。接下来，我们将讨论IntenServices、绑定服务和外部服务的创建，这些服务即使在用户不与其交互时也可以在后台运行。在更高级的阶段中，您将使用Android NDK创建能够在本机代码中执行CPU密集型任务的后台任务。

然后将引导您完成使用HTTP协议或Google GCM平台与远程服务进行异步交互的过程。最后，我们将介绍RxJava，这是一个流行的异步Java框架，用于以简洁和被动的方式编写工作。
