Step-by-step Android Wear Application Development

Book Description

Step-by-step tutorials that leads you through the essential concepts and techniques for developing Android Wear applications.

Have you ever thought to yourself: “I wish I had learned to develop iPhone apps when the iPhone first came out”? Very few people had the foresight to act on the fact that computing platforms are continuously getting smaller, cheaper, faster, and more intimate. Computers have evolved from fixed room-sized machines to desktops, laptops, and handheld devices. The same disruptive transition is about to take place again. Only this time, instead of taking your smartphone out of your pocket, the computer has become wearable.

This is a great time to start learning Android Wearable development. Consumers will come to embrace smartwatches because they will be relatively unobtrusive and will allow them to do things that smartphones can’t.

What you will learn:

• Create native wearable apps using the Android SDK
• Build consistent UI layouts using Cards and CardFragments
• Learn all about the Wearable UI Library to build exciting and engaging apps
• Master the notification framework. Build notifications for handhelds apps that are automatically extended to Android Wear and learn how to build custom notifications on wearables to better support your brand
• Working with wearable sensors
• Use the Wearable Data Layer API to create native apps that can communicate securely with a paired smartphone
• Includes three exciting projects: 1) Build a car catalog app to browse through vehicles, take notes on them, and schedule test drives all within arms reach, 2) Build a fitness app to start, pause or stop a workout session and 3) Build an animated dice game using the handheld device as a remote control or the wearable’s accelerometer sensor to detect shake gestures in order to roll a die. You will learn how to animate shapes, establish a data connection between the mobile and Wear devices, and display a history of dice roll outcomes on the handheld device.

Who is this book for?

This book is for intermediate developers who know the basics of Android application development and want to quickly get up to speed and start developing apps for Android Wear. If you are a complete beginner to Android, don’t worry. The step-by-step tutorials are easy to follow and each exercise is followed by an in-depth source code explanation. This book is the best way to get a head start now developing apps for Android Wear.

“Alex has written a masterful collection of tutorials, patterns, tips & tricks, and helpful insider hints that developers at any level will appreciate. The example apps are easy yet challenging, fun yet practical, and put together using best practices. You’ll really come away with a strong sense of how to build effective experiences for Google wearables.”

书名：Step-by-step Android Wear Application Development

循序渐进的教程，引导您了解开发Android Wear应用程序的基本概念和技术。

你有没有想过自己：我希望我在iPhone刚问世时就学会了开发iPhone应用程序？很少有人有远见卓识地采取行动，因为计算平台正在不断变得更小、更便宜、更快、更亲密。计算机已经从房间大小固定的机器发展到台式机、笔记本电脑和手持设备。同样的颠覆性转变即将再次发生。只是这一次，电脑不再是从口袋里掏出智能手机，而是变得可穿戴了。

这是开始学习Android可穿戴设备开发的绝佳时机。消费者将逐渐接受智能手表，因为它们将相对低调，并允许它们做智能手机做不到的事情。

您将了解到的内容：

• 使用Android SDK创建本地可穿戴应用程序
• 使用Cards和CardFragments构建一致的用户界面和布局
• 了解有关可穿戴用户界面库的所有信息，以构建令人兴奋和引人入胜的应用程序
• 掌握通报框架。为自动扩展到Android Wear的手持设备应用程序构建通知，并了解如何在可穿戴设备上构建自定义通知，以更好地支持您的品牌
• Working with wearable sensors
• 使用可穿戴数据层API创建可与配对的智能手机安全通信的原生应用程序
• 包括三个令人兴奋的项目：1)构建一个汽车目录应用程序来浏览车辆，对它们做笔记，并安排所有测试驾驶都在伸手可及的范围内；2)建立一个健身应用程序来开始、暂停或停止锻炼过程；3)建立一个动画骰子游戏，使用手持设备作为遥控器或可穿戴设备的加速计传感器来检测摇晃的手势以便掷骰子。您将学习如何为这些形状设置动画，在移动设备和Wear设备之间建立数据连接，并在手持设备上显示掷骰子结果的历史记录。

这本书是给谁看的？

本书面向那些了解Android应用程序开发基础知识并希望快速入门并开始为Android Wear开发应用程序的中级开发人员。如果您完全是Android的初学者，请不要担心。这些循序渐进的教程很容易理解，每个练习之后都会有深入的源代码解释。这本书是现在为Android Wear开发应用程序的最好方式。

Alex写了一本精湛的教程、模式、技巧和有用的内幕提示的集合，任何级别的开发人员都会欣赏。这些示例应用程序简单但具有挑战性，有趣但实用，并使用最佳应用实践组合在一起。你真的会对如何为谷歌可穿戴设备打造高效体验有很强的认识。
