2、、 1系统得可行性分析可行性研究就是为了弄清楚系统开发得项目就是不就是可以实现与值得进 行研究得过程，实际上就是一次大大简化系统分析与系统设计得过程，所以，进行可执行性得分析就是非常必要得， 也就是很重要得，经过最初得设计目标与进 行得实时调查得出以下四点得可行性分析：(1)技术可行性：Eclipse + Andro i d ADT得技术已经较为成熟，通 过S UN公司(现被O RCEL公司收购)推出得跨平台、动态得 JAVA语言进行 开发。(2)运行可行性：该系统需要Andro i d虚拟机环境，Ec l i p se中安装AD T, DDMS等Google An droid相关插件.其运行

3、环境已经相当稳定，它功能丰富, 包括了完备得A ndroid程序得编码、调试、测试与发布功能，其中支持所有An droid应用开发相关技术，包括SQLit e ,Skia ,3D制作,A n droid XML,能够很好 得发布A ndro id得应用程序A PK包。( 3) 法律可行性：因为就是自主开发设计,所以不会构成侵权,在法律上就是可行得。通过以上得可行性分析，将采用Ecl i pse+ A n dro i d ADT + D DMS技 术，运用JAV A语言进行系统得开发。1、2系统得需求分析根据分析需求,这个系统必须实现以下得功能(1)实现简单得数字计算功能.作为计算器，其核心就就
