Android快速开发不可或缺的11个辅助类

android蓝牙简单入门，只涉及打开蓝牙，关闭蓝牙，搜索配对蓝牙，显示蓝牙可见

说明：  强烈推荐好用的卷积码编码,维特比译码和软判决,本代码简易可行,(Good convolutional code coding, Viterbi decoding and soft decision are highly recommended. This code is simple and feasible.)

【实例简介】

个人开发的 一个基于android平台的LBS 旅游记忆项目 是社区应用 有地图位置的服务 记忆自己的旅游足迹 分享给好友...使用了闪屏，等各种绚丽的界面，数据库使用contentProvider来提供通过uri和界面交互。有注释，适合新手学习。(Personal development of a tourism based on the android platform of LBS applications have memory map of the project is the location of community services to share the memory footprint of their travel to friends ...)

android 的一些功能特效 很实用的。(android special effects)

一款连连看的游戏，闲暇时分娱乐消遣，游戏说明，通过一根线两个相同的水果链接起来就可以消除点，简单易上手！

监听自身应用卸载，并在卸载之后，使用libcurl三方库进行一次三方请求，或者启动网页的实例工程。

ZBar库的android编译工程，扫码速度相当快。可以参考。(Sweep ZBar library android compile the project, code is quite fast. You can refer to. )
