android_sdk2.2_samples开篇

本文探讨了Android SDK自带示例的重要性,指出这些示例能帮助开发者了解新特性、提高编码规范,并作为新版本的第一个样例。作者将分享自己多年开发经验中总结的观点。

       一直以来,没有人给大家讲解SDK自带的例子。我不知道是大家觉得里面的例子还过于简单还是别的什么原因。但是我个人认为,大家都走了一个误区,android_SDK自带的例子很知道大家去学习,我的理由有以下几点。

       第一,每个SDK自带的例子都包含了这个版本的新特性的例子,这是我们了解这些新特性最好的资源。

       第二,SDK自带的例子并不是非常简单,很多东西很多开发者都没有见过。

       第三,这些例子也算是高手写的,至少他们的水平会比我们初学者高。这是一个学习写代码规范的好资源。

       第四,自带的例子永远会是一个新版本的第一个samples。

       如果你赞同我的这些观点,我可以往我以后的帖子看下去。这个版块的帖子或多或少有你值得学习的东西,毕竟我开发android也有许久了。当然,我在写的时候难免有些误区,希望大家如果发现一些问题可以及时纠正我。

       OK,接下来大家一起努力。

List of Sample Apps The list below provides a summary of the sample applications that are available with the Android SDK. Using the links on this page, you can view the source files of the sample applications in your browser. You can also download the source of these samples into your SDK, then modify and reuse it as you need. For more information, see Getting the Samples. API Demos A variety of small applications that demonstrate an extensive collection of framework topics. Backup and Restore A simple example that illustrates a few different ways for an application to implement support for the Android data backup and restore mechanism. Bluetooth Chat An application for two-way text messaging over Bluetooth. BusinessCard An application that demonstrates how to launch the built-in contact picker from within an activity. This sample also uses reflection to ensure that the correct version of the contacts API is used, depending on which API level the application is running under. Contact Manager An application that demonstrates how to query the system contacts provider using the ContactsContract API, as well as insert contacts into a specific account. Home A home screen replacement application. JetBoy A game that demonstrates the SONiVOX JET interactive music technology, with JetPlayer. Live Wallpaper An application that demonstrates how to create a live wallpaper and bundle it in an application that users can install on their devices. Lunar Lander A classic Lunar Lander game. Multiple Resolutions A sample application that shows how to use resource directory qualifiers to provide different resources for different screen configurations. Note Pad An application for saving notes. Similar (but not identical) to the Notepad tutorial. SampleSyncAdapter Demonstrates how an application can communicate with a cloud-based service and synchronize its data with data stored locally in a content provider. The sample uses two related parts of the Android framework — the account manager and the synchronization manager (through a sync adapter). Searchable Dictionary A sample application that demonstrates Android's search framework, including how to provide search suggestions for Quick Search Box. Snake An implementation of the classic game "Snake." Soft Keyboard An example of writing an input method for a software keyboard. Spinner A simple application that serves as an application-under-test for the SpinnerTest sample application. SpinnerTest An example test application that contains test cases run against the Spinner sample application. To learn more about the application and how to run it, please read the Activity Testing tutorial. TicTacToeLib An example of an Android library project that provides a game-play Activity to any dependent application project. For an example of how an application can use the code and resources in an Android library project, see the TicTacToeMain sample application. TicTacToeMain An example of an Android application that makes use of code and resources provided in an Android library project. Specifically, this application uses code and resources provided in the TicTacToeLib library project. Wiktionary An example of creating interactive widgets for display on the Android home screen. Wiktionary (Simplified) A simple Android home screen widgets example.
