In order to avoid fetting the schedule and missing some important affairs, people always carry memos with themselves. Nowadays, there are plenty of applications on the smart phones and technicians have developed many similar memo applications for people to use. Basically, Android platform is an open source and free 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。 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. Key words: Android, memo, multimedia, alarm clock 目 錄 摘要 ........................................................................................................................
