Android开发入门学习笔记

Getting Started Welcome to Training for Android developers. Here you'll find sets of lessons within classes that describe how to accomplish a specific task with code samples you can re-use in your app. Classes are organized into several groups you can see at the top-level of the left navigation. This first group, Getting Started, teaches you the bare essentials for Android app development. If you're a new Android app developer, you should complete each of these classes in order:			有言在先 作为一名Windows程序员，不管是为以后的职业生涯打算，还是为了扩展技术视野，学习和掌握一些终端的开发技术总是有益无害的。而作为一名Android开发的新手，前辈给我的意见是“先不用急着买这书买那书，抓紧时间把官网上的开发入门教程看完了再说”。 左边的英文目录，就是官网上的开发入门教程。而以下的这些文章，并不是对于英文教程的翻译，而是我在学习英文教程过程中自己的一些心得体会和批注，可能画蛇添足，但愿狗尾续貂。 在启动学习之前，前辈给我的两点意见是可以和大家分享的： 1. 不要急，一步一步地跟着教程走； 2. 不要浮躁，老老实实地按照教程做。
Building Your First App			构建你的第一个App
After you've installed the Android SDK, start with this class to learn the basics about Android app development.	Creating an Android Project Running Your Application Building a Simple User Interface Starting Another Activity		在你安装了Android SDK之后，开始这个课程以便学习android 程序开发的基本知识。	创建一个Android工程 运行你的应用 构建一个简单的用户界面 启动另一个活动
Managing the Activity Lifecycle			生命周期的管理
How Android activities live and die and how to create a seamless user experience by implementing lifecycle callback methods.	Starting an Activity Pausing and Resuming an Activity Stopping and Restarting an Activity Recreating an Activity		在这里，你将了解到android activities 是如何live和die的，以及如何利用生命周期回调函数完成无缝的用户体验。	启动Activity 暂停和恢复 Activity 停止和重启Activity 重建Activity
Supporting Different Devices			多设备支持
How to build your app with alternative resources that provide an optimized user experience on multiple device form factors using a single APK.	Supporting Different Languages Supporting Different Screens Supporting Different Platform Versions		如何通过配置多样的资源文件来构建程序，以优化一个APK文件在不同设备上的用户体验。	多语言支持 多屏幕支持 不同平台版本支持
Building a Dynamic UI with Fragments			通过片段创建灵活的用户界面
How to build a user interface for your app that is flexible enough to present multiple UI components on large screens and a more constrained set of UI components on smaller screens—essential for building a single APK for both phones and tablets.	Using the Support Library Creating a Fragment Building a Flexible UI Communicating with Other Fragments		如何灵活的构建程序的用户界面以在大屏设备上展现复杂的UI组件，而在小屏设备上展现相对紧凑的UI组件——这在用同一个APK文件来适配手机和平板上显得非常重要。	利用android支持的库 创建一个片段 建立一个灵活的用户界面 与其他片段交互
Saving Data			数据存储
How to save data on the device, whether it's temporary files, downloaded app assets, user media, structured data, or something else.	Saving Key-Value Sets Saving Files Saving Data in SQL Databases		如何在设备上储存诸如临时文件、下载的app资源、用户媒体数据、结构化数据等你想存的东西
Interacting with Other Apps			与其他应用程序进行交互
How to build a user experience that leverages other apps available on the device to perform advanced user tasks, such as capture a photo or view an address on a map.	Sending the User to Another App Getting a Result from the Activity Allowing Other Apps to Start Your Activity		如何利用设备上其他可用的程序完成诸如拍照，查看地图上的位置等用户行为。	让用户转移到另一个应用程序 从另一个Activity中取回反馈结果 允许其他应用程序去启动您的Activity
Sharing Content			内容共享
How to take your app interaction to the next level by sharing information with other apps, receive information back, and provide a simple and scalable way to perform Share actions with user content.	Sending Content to Other Apps Receiving Content from Other Apps Adding an Easy Share Action		如何通过与其他应用共享数据，接受来自其他应用的数据和提供一种简单而具有可扩展性的方式来完成分享用户内容的动作（好绕口）来把你的应用提高到更高的层次——社交应用（误，不过这样感觉牛X点）。	将内容发送到其他应用程序 从其他应用程序接收内容 添加一个简单的共享行动
