1、精選優質文檔-傾情為你奉上Android應用程序開發實驗報告學 號： 學生: 會會 指導教師： 齊兵輝 提交時間： 2015.11.10 目錄第一章 系統分析與設計1.1系統的可行性分析可行性研究是為了弄清楚系統開發的項目是不是可以實現和值得進行研究的過程，實際上是一次大大簡化系統分析和系統設計的過程，所以，進行可執行性的分析是非常必要的，也是很重要的，經過最初的設計目標和進行的實時調查得出以下四點的可行性分析：（1）技術可行性：Eclipse + Android ADT的技術已經較為成熟，通過SUN公司（現被ORCEL公司收購）推出的跨平臺、動態的JAVA語言進行開發。（2）運行可行性：該系

2、統需要Android虛擬機環境，Eclipse中安裝ADT，DDMS等Google Android相關插件。其運行環境已經相當穩定，它功能豐富，包括了完備的Android程序的編碼、調試、測試和發布功能，其中支持所有Android應用開發相關技術，包括SQLite，Skia，3D制作，Android XML，能夠很好的發布Android的應用程序APK包。（3）法律可行性：因為是自主開發設計，所以不會構成侵權，在法律上是可行的。通過以上的可行性分析，將采用Eclipse+Android ADT + DDMS技術，運用JAVA語言進行系統的開發。1.2 系統的需求分析根據分析需求，這個系統必須實
