简单介绍
一个好的Android应用开发框架，能够加快Android开发速度，今天笔记基于很多开源项目自写了一款Android应用框架。
内容
框架包含：界面管理（Activity管理）、数据库操作（orm框架、加密等）、http交互、缓存管理、下载管理、路径管理、日志输出、网络管理、系统命令、加解密、stl容器、任务管理、奔溃管理、存储管理、其他辅助管理…。
解决思路例如以下：
界面管理：使用Stack记录Activity的执行轨迹，并在每一个Activity加入一个广播处理自己定义事件。
private static Stack<Activity> mActivityStack;//进行Activity执行记录数据库管理：对数据库的操作要求orm框架、加解密等。採用的是greendao和sqlcrypt开源项目解决。
http交互：实现http交互方式有同步、异步操作。採用的是android-async-http开源项目解决。
缓存管理：实现缓存方式有内存缓存、磁盘缓存。当中内存缓存仅仅针对图片处理。磁盘缓存是针对某文件夹。实现的方式有：先进先出、最大量、使用频率等。
下载管理：下载管理方式有多线程下载、单线程下载。
路径管理：简单的说就是对程序的文件夹管理，分图片、视频、音频、缓存文件夹等。
日志输出：基于Log的管理（分调式、公布模式和文件输出、log输出）。
网络管理：2G、3G、4G等联网方式不同的管理和监听。
系统命令：直接命令执行。
加解密：aes、base64、des、md5等加密方式。
stl容器：重写stl部分容器。
任务管理：基于AsyncTask任务的管理。
奔溃管理：捕捉奔溃信息，并提供发送接口。採用的是acra方法解决。
存储管理：主要是SharedPreferences和Properties的管理。
其他辅助管理：版本号、内存、手机格式、字符串操作……等等。

相关測试代码：

此框架參考了ThinkAndroid，在写此项目之前，笔者一直使用ThinkAndroid框架开发项目。所以非常多思想来源于此。Think框架介绍例如以下：
ThinkAndroid是一个免费的开源的、简易的、遵循Apache2开源协议公布的Android开发框架，其开发宗旨是简单、高速的进行Android应用程序的开发，包含Android mvc、简易sqlite orm、ioc模块、封装Android httpclitent的http模块,具有高速构建文件缓存功能，无需考虑缓存文件的格式，都能够非常轻松的实现缓存，它还基于文件缓存模块实现了图片缓存功能。在android中载入的图片的时候，对oom的问题。和对载入图片错位的问题都轻易解决。他还包含了一个手机开发中常常应用的有用工具类，如日志管理。配置文件管理，android下载器模块，网络切换检測等等工具。
