摘要 现在移动设备呈几何形增加，移动设备的演化增加了各种移动设备的应用程序开发，这些移动设备可以成为承载WEB服务的客户端，移动的硬件和软件平台形式允许更快和更丰富的应用程序的运行。本文所介绍的通话录音系统趋于国际化也被越来越多的人接受 ，自2000年以来，全国手机基本上普遍都具有通话录音功能，可将短暂通话记录下来，一般作为法庭重要政务和不可轻视的证据，也可适当看做娱乐。手机录音直接就可以保存在手机SD卡上，需要的时候可以直接调出来，很方便。 因为目前手机市场已经出现了明显的Android一家独大趋势，所以本系统选择了Android平台进行开发。本论文首先给出了课题的研究背景，对Android平台做了简单的介绍，通过介绍，可以让读者了解其平台的基本框架以及基本的平台开发技术，在此基础上分析了手机通话录音系统Android客户端程序的基本架构以及各个模块的解决方案，实现通话录音的打开、关闭、播放、删除、保存、选择格式等功能。 关键字：移动设备、通话录音系统、Android Abstract Now the mobile device is geometric increase, evolution of mobile devices increase the application development of various mobile devices, these devices can be hosting the WEB service client, allowing faster and more extensive application of mobile hardware and software platform running .Call recording system described in this article to be internationalization is accepted by more and more people, since 2000, the national mobile phone basically universal has call recording function, can be recorded as a short talk, the General Court Affairs and important evidence, can also be appropriate as entertainment. Mobile phone recording directly can be kept in the mobile phone SD card, when necessary, can be directly transferred out, very convenient. Because the mobile phone market has appeared obvious Android alone big trend, so the system selected Android development platform. This paper first presents the research background of the subject, the Android platform is introduced, through the introduction, so that readers can understand the basic framework of the platform as well as the basic platform development technology, based on the analysis of the basic architecture of mobile phone call recording system Android client program and each module of the solution, realizing call recording open, close, delete, save, play, choose Format etc.. Keywords: mobile equipment, call recording system, Android  目 录 1.绪论 1 1.1研究背景 1 1.2研究概况与发展趋势 1 2.需求分析 1 2.1可行性分析 1 2.1.1操作
