【正文】 e of charge, so it can reduce the cost of software effectively and make every user to gain information what they wanted freely. Therefore, from the actual demands, developing a multifunctional memo application which based on the Android platform will gain a practicability and market prospect in the future. This paper has analyzed the system architecture and ponent model of Android platform, and then parses the important part of the Android API and application configuration, as well as the introduction of the Intent and mechanism of life cycle. On this basis, we design and develop this multifunctional memo which based on the android platform. This topic is developing application level which coordinated with API level and based on the Android system. With development environment of SDK, using eclipse as an IDE development environment, it uses objectoriented method, and selects Java language as the programming language and SQLite database. This system has a friendly interface, convenient operation, good expandability and maintainability。錄音記事功能、拍照記事功能以及錄像記事功能，使用戶能隨時(shí)隨刻記錄下重要信息。 本課題研究的多功能備忘錄的設(shè)計(jì)開(kāi)發(fā)是為了最大程度上方便人們記錄生活中的重要事情。 本系統(tǒng)界面友好、操作便捷，具有良好的可擴(kuò)展性和可維護(hù)性 。在此基礎(chǔ)上，基于 Android 平臺(tái)設(shè)計(jì)和開(kāi)發(fā)多功能備忘錄軟件。因此，從實(shí)際需求 出發(fā)，開(kāi)發(fā)一款基于 android 平臺(tái)的多功能備忘錄應(yīng)用具有很大的實(shí)用性和廣大的市場(chǎng)前景?，F(xiàn)在智能手機(jī)上的 APP 多種多樣，技術(shù)人員已開(kāi)發(fā)出很多類似備忘錄功能的 APP。 本科生畢業(yè)設(shè)計(jì)（論文） 題 目： 基于 Android 的多功能備忘錄 的設(shè)計(jì)與實(shí)現(xiàn) 姓 名： 學(xué) 號(hào)： 學(xué) 院： 數(shù)計(jì)與計(jì)算機(jī)科學(xué)（軟件）學(xué)院 專 業(yè)： 軟件工程 年 級(jí)： 2020 級(jí) 指導(dǎo)教師： （簽名） 2020 年 5 月 23 日 基于 Android 的多功能備忘錄的設(shè)計(jì)與實(shí)現(xiàn) 摘 要 隨著科技的不斷發(fā)展，智能手機(jī)已成為人們?nèi)粘Ｉ钪斜夭豢缮俚脑O(shè)備。為防止忘記日程安排而錯(cuò)過(guò)一些重要的事務(wù)，人們隨身攜帶備忘錄。并且 Android 平臺(tái)基本上是開(kāi)源且免費(fèi)的，能夠有效降低軟件的成本，最終讓每個(gè)用戶能夠自由地獲取已開(kāi)發(fā)的 APP。 本文內(nèi)容包括了對(duì) Android 平臺(tái)的系統(tǒng)架構(gòu)和組件模型的分析，對(duì) Android 中的重要 API 和應(yīng)用構(gòu)成的解析，以及對(duì) Intent 和生命周期的機(jī)制的介紹。本課題基于 android 的系統(tǒng)通過(guò) API 配合進(jìn)行應(yīng)用程序?qū)哟蔚拈_(kāi)發(fā)，在 SDK 的開(kāi)發(fā)環(huán)境中，使用 eclipse 等作為 IDE 開(kāi)發(fā)環(huán)境，采用面向?qū)ο蠓椒ǎx擇 java 語(yǔ)言作為編程語(yǔ)言，數(shù)據(jù)庫(kù)選用 SQLite 數(shù)據(jù)庫(kù)。系統(tǒng)經(jīng)過(guò)測(cè)試，可以穩(wěn)定運(yùn)行，能夠滿足手機(jī)用戶的基本需求。該備忘錄除了具備記事本最基本的增刪改查功能外，還擁有個(gè)性化的鬧鈴實(shí)時(shí)提醒功能，能對(duì)每一條記錄分別設(shè)置不同的鬧鐘提醒。 關(guān)鍵詞：安卓，備忘錄，多媒體，鬧鐘 Design and implementation of multifunctional memorandum based on Android platform Abstract With the advancement of science technology, smart phones have bee an integral device in people39。 after tested system, it can operate stably, and satisfy the basic needs of mobile phone users. For the sake of convenience for people to record something important in their daily life, this research mainly investigates the design and development of multifunction memo. This memo application is not only having the primary function of adding, deleting, modifying and inquiry as notepad, but also has a personalized alarm clock function, which can set different alarm reminder for each record. And the memo also be designed with recording function, photo function and video function so that users can record the important information at any time.
