1、ApiDemos——android Api调用实例

   为了让Android应用开发的人员能更好的学习Android平台,Google为Android应用开发提供了API调用的例子,应有尽有啊,各种示例

2、BackupRestore——资源备份

   把应用程序的数据存储到云端服务器上面

3、BluetoothChat——蓝牙聊天

 这个例子是对蓝牙功能的扩展,实现基于蓝牙的实时数据传输(包括聊天功能),其中涉及到扫描附近可用设备、初始化设备间蓝牙链接和传送实时数据。

   Bluetooth 是几乎现在每部手机标准配备的功能,多用于耳机 mic 等设备与手机的连接,除此之外,还可以多部手机之间建立 bluetooth 通信。

4、ContactManager——通信录管理

5、CubeLiveWallpaper——立方体动态壁纸

 CubeLiveWallpaper用于实现一个动态壁纸 显示一个不停转动的立方体。长按手机主界面 在弹出的对话框中 点击动态壁纸 在动态壁纸列表中可看到!

6、GestureBuilder——手势识别

 根据用户在屏幕上画的不同图形可以进行相应的操作。例如把画X可以退出程序;画不同的数据可以直接拨号。

7、Home——launcher

8、JetBoy——飞船射击游戏

  主要是如何使用JetPlayer类

9、LunarLander——登录月球小游戏

这是一个登月游戏实例,演示了一个类似于登陆月球的小游戏,可以通过方向键和点火时机控制画面上的飞船

它与snake的“定时器+系统调用onDraw”架构相比,由于采用了“多线程+强制自行绘制”的架构思路,因而更为实用.

10、MultiResolution——多分辨率

包括两方面的内容,1)阐述如何巧妙的根据多种屏幕显示标准来匹配特定的资源目录。2)针对不同Android SDK版本的用户优化应用程序。

11、NotePad——记事本

   这个例子包含了与Live Folders相关的技术

    NotePad是一个记事本程序,此程序可以实现新建、编辑和删除文档等操作。本实例应用了SQLite的数据存储和编辑,并使用了ContentProvider等方面的信息。

12、SampleSyncAdapter——帐号同步

      手机setting里的帐号与同步

13、SearchableDictionary——带提示功能的搜索

14、SkeletonApp——视图组件

   本实例展示了如何在Android中应用提供的视图组件,例如常见的EditRext、Button、ImageView和菜单等

15、Snake——贪吃蛇游戏

 Snake是贪吃蛇演示实例,这是一款经典的游戏,使用手机方向键可以对游戏进行控制。

16、SoftKeyboard

   SoftKeyboard是一个软键盘实例,此实例演示了如何将软键盘绑定到输入框输入事件上。当焦点到输入框上时,将自动显示软键盘。

17、Spinner——下拉框实例

18、TicTacToeMain、TicTacToeLib——android库项目开发实例

19、VoiceRecognitionService——语音识别服务

20、WiktionarySimple——维基例程

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.
