随着智能手机发展越来越迅猛，手持智能手机的人越来越多，尤其是价格合理的android手机。人们已经习惯用手机来处理一些事情，尤其用手机的记事本或者标签来记录日常工作的事物，在这种情况下，开发一款基于android平台的简单实用的记事本很有必要，可以在很大程度上方便人们的生活。

此次课题研究的目标是在android系统上，实现一款能够流畅运行记事本应用，并支持多种记事方式。目前来说，利用android 强大的SDK工具包以及eclipse完善的开发功能，可以比较容易的实现这样一款应用。论文主要论述了这款应用的需求场景以及系统设计和实现，其中这款应用具有两大特色：第一个特色是可以添加闹钟提醒，并且可以设置闹钟提醒次数和提醒次数；第二个特色是同时支持音频记事和图片记事，并且图片记事灵活，可以添加多张图片。

论文中最终实现了一款基于android系统的记事本应用YYnote，此应用的主要功能有添加文本，添加多张图片，录制音频以及为记事添加闹钟提醒，同时还可以分享记事，整个应用在android4.0上运行流畅。
