| With the popularity of the smartphone, Android platform becomes one of the majorplatforms in the mobile communication field. Android application development shows apopular trend in the mobile application market nowadays. The operating system of Android iscompatible with touch-available function so that the applications of Android are convenientand easily used, which has been the most highlighted advantage. Among so many differentkinds of applications, memorandum is a popular kind of simple and practical software. Thedevelopment of memorandum involves realization of JAVA project, using of database,software engineering.The current memo on phones has clearly insufficient on time sorting and importanceclassification. They are lack of the function of classification. From this point of departure, thisapplication will integrate the classification function and add some convenient functions at thesame time. This article is to introduce the developing process of the application in Androidversion4.2by eclipse ADT. In developing procedure, Time Classification, ImportancePartition, Gesture Control and Interface personalization will be accomplished by coding stepby step．At the same time, the software can realize online cloud synchronization interface.The database used in this application is SQLite database which is common in Android system.The data of the software is saved in local database. They can be transformed to json for lateronline synchronization. The advantage of the database is simple, stable and has goodcompatibility. What’s more, the application has complete and elegant interface and goodinteraction with users.This paper begins with demand analysis and then gradually improves the varioussoftware components details of memorandum in depth. The next step is coding to realize thefunction. Finally, we do test and acceptance of the application. After accomplishing thecomplete memorandum function, the online-synchronization interface is kept for later work. |
