摘 要

Android作为一个针对移动设备的操作系统和软件平台，随着科技的进步，通信技术的发展，以及智能手机的兴起。作为开源系统的Android拥有着独特的优势。与此同时，基于Android平台的应用软件开发快捷简单，用户体验度良好等优点。Android渐渐成为了占有市场最大比重的移动平台操作系统。

手机录音系统是智能手机的重要组成部分，提高手机录音系统信息的安全性也是手机发展的必然趋势。急剧膨胀的信息化发展开创了新的发展局面，为了适应新的发展形势, 解决传统手机录音模式的信息安全性差，效率低，操作繁琐等基本问题。因而开发新的高效、安全的手机录音系统已经迫在眉睫。由于目前手机录音系统具有以下几个突出重点的特性：操作过于繁琐、信息安全性差等，通过分析手机录音系统的操作流程，结合当前消费者对手机录音系统的功能需求，有效地将操作流程简化并提升录音信息的安全性，从而开发出一个更加高效，更加符合消费者需求的手机录音系统，同时也更加适应当前智能手机的发展需要。传统的手机录音系统的模式无法适应快速增长的手机录音系统的需要，同时随着互联网的不断发展，信息的透明程度越来越高，必须尽快开发基于安卓的手机录音系统从而安卓手机录音系统的实用性和安全性。从而更好的贴合消费者的需求并适应安卓手机的发展。本论文主要实现手机录音系统的功能，切实实现了手机录音功能，以及提高信息的安全性的功能。

本文设计基于Android的手机录音系统，实现对录音信息的安全性提供可靠保证的同时保证其它功能的正常运作。作者在本文中主要承担的工作包括：

1. 结合手机录音系统进行需求分析，确立系统功能，规划系统范围，确立模板所要完成的任务；
2. 系统构架的建立、设计内容与研究思路，数据结构的建立和工作流程的整体架构；
3. 搭建开发环境，提供开发平台，完成项目的编码和后续的测试工作。

Android as an operating system and software platform for mobile devices, with advances in technology, development of communication technology, as well as the rise of smart phones. As Android open source system has a unique advantage. At the same time, based on android platform application development faster and easier, the advantages of a good user experience. Android market share has gradually become the largest share of the mobile platform operating system.

Phone recording system is an important component of smart phones, to improve the security of an inevitable trend information phone recording system is mobile phone development. The rapid expansion of information technology development to create a new development of the situation, in order to adapt to new developments, to solve the traditional phone recording mode information security is poor, inefficient, complicated operation and other basic issues. Thus the development of new efficient and secure phone recording system is imminent. Due to the current phone recording system has the following salient features focus: too cumbersome, and poor information security, operational processes through the analysis of the phone recording system, combined with the current consumer demand for mobile phones recording systems function effectively simplify the operation process and enhance the security of recording information in order to develop a more efficient, more in line with consumer demand for mobile recording system, but also more responsive to the development needs of current smart phones. The traditional mode phone recording system can not meet the needs of the fast-growing mobile phone recording system, but with the continuous development of the Internet, more and more high level of transparency of information, must be developed as soon as Android-based phone recording system recording system so Android phones practicality and safety. In order to better fit the needs of consumers and to adapt to the development of Android phones. In this thesis, to achieve functional phone recording system, the practical realization of the phone recording function, as well as improve safety function information.

This design Android-based phone recording system, recording information on security at the same time provide a reliable guarantee to ensure the normal functioning of other functions. The author of this article is mainly responsible for the work include:

1、 with the phone recording system needs analysis to establish the system function,system-wide planning, establishing the template to complete the task;

2、 the establishment, content and design idea to establish and workflow data structure overall architecture of the system architecture;

3、 setup the development environment to provide a development platform, complete coding and subsequent testing of the project.
