編輯：關於Android編程
一個好的Android應用開發框架，可以加快Android開發速度，今天筆記基於許多開源項目自寫了一款Android應用框架。
框架包括：界面管理（Activity管理）、數據庫操作（orm框架、加密等）、http交互、緩存管理、下載管理、路徑管理、日志輸出、網絡管理、系統命令、加解密、stl容器、任務管理、奔潰管理、存儲管理、其它輔助管理…。
解決思路如下：
界面管理：使用Stack記錄Activity的運行軌跡，並在每個Activity添加一個廣播處理自定義事件。
private static Stack mActivityStack;//進行Activity運行記錄數據庫管理：對數據庫的操作要求orm框架、加解密等，采用的是greendao和sqlcrypt開源項目解決。
http交互：實現http交互方式有同步、異步操作。采用的是android-async-http開源項目解決。
緩存管理：實現緩存方式有內存緩存、磁盤緩存。其中內存緩存只針對圖片處理，磁盤緩存是針對某目錄，實現的方式有：先進先出、最大量、使用頻率等。
下載管理：下載管理方式有多線程下載、單線程下載。
路徑管理：簡單的說就是對程序的目錄管理，分圖片、視頻、音頻、緩存目錄等。
日志輸出：基於Log的管理（分調式、發布模式和文件輸出、log輸出）。
網絡管理：2G、3G、4G等聯網方式不同的管理和監聽。
系統命令：直接命令運行。
加解密：aes、base64、des、md5等加密方式。
stl容器：重寫stl部分容器。
任務管理：基於AsyncTask任務的管理。
奔潰管理：捕捉奔潰信息，並提供發送接口。采用的是acra方法解決。
存儲管理：主要是SharedPreferences和Properties的管理。
其它輔助管理：版本、內存、手機格式、字符串操作……等等。

} 此框架參考了ThinkAndroid，在寫此項目之前，筆者一直使用ThinkAndroid框架開發項目，所以很多思想來源於此。Think框架介紹如下：
ThinkAndroid是一個免費的開源的、簡易的、遵循Apache2開源協議發布的Android開發框架，其開發宗旨是簡單、快速的進行Android應用程序的開發，包含Android mvc、簡易sqlite orm、ioc模塊、封裝Android httpclitent的http模塊,具有快速構建文件緩存功能，無需考慮緩存文件的格式，都可以非常輕松的實現緩存，它還基於文件緩存模塊實現了圖片緩存功能，在android中加載的圖片的時候，對oom的問題，和對加載圖片錯位的問題都輕易解決。他還包括了一個手機開發中經常應用的實用工具類，如日志管理，配置文件管理，android下載器模塊，網絡切換檢測等等工具。
