Multi-functional Diary The Design And Implementation

Android system which uses the Linux Kernel is an open-source smart phone operating system launched by Google in2008. The system consists of the operating system,middleware, user interface and application software. The Android system uses an open architecture, provides a large number of graphical components,offers multimedia support and combines a powerful browser,as well as a good development of software and a debugging environment,all of which provides the Android platform with a satisfying scalability. Especially,today’s extensive demand for multi-functional smart phone makes it have a broad prospect,which is very attractive to software developers.In this paper, taking full account of the superiority of the Android platform and the actual needs of the smart phone users,the multi-functional diary is designed and implemented based on the Android platform. The design and Implementation of the system mainly include the following aspects:1.Based on the Android platform, the multi-functional diary framework is established, which contains a mood diary,voice diary,video diary,photo albums diary,and personal account.2.The diary system needs analysis is undertaken,the basic functions of each module is built,and the expected results are predicted.3.The functions of these five modules are achieved by using object-oriented programm ing methods.4.The hardware and software testing is achieved respectively. The entire diary system is improved on the basis of the successful test of each module.The diary software interface is friendly,easy to operate,and has good scalability and maintainability. After testing, the software is safe,reliable,and stable operation.
