The Design And Implementation Of Single Phone Double Numbers Call Application Based On The Platform Of Android

Nowadays, with the fast development of the telephone communication, more and more people are busy with communication business. A cell phone can’t meet people’s need, however, that too many phones will also bring convenience problem. In order to satisfy the users’requirement, TianZhou communication company have designed a soft application based on Android system, which placed double numbers in a single card. This kind of product is not only used by the main number of SIM card for call, but also used by a vice number given by the company to satisfy the users’need. The feature of the product named Single Card Double Number is that the user can install it when they need, and also can unload it when they dislike. The application does not make any change in the hardware which bring much convenience to the user.The product named Single Card Double Number is a client application based on the Android platform. The system adopt traditional design model-MVC, using MySQL as a database for storing data, applying HTTP protocol for communicating. The system adopt SAX method for analyzing XML and integrates Alipay client to implement payment function. In the Windows development environment, the system takes Eclipse as a development tool, using JAVA and ADK for application program developing. During the development of the project, firstly, the developer needs to make analysis to the system for acquiring the users’requirement, then defines the system main function. Secondly, the system need to design the frame, the system consists of five packages, such as interface, communication, analysis, tool and storage package. By a detailed design, it has realized the functions of every sub-models. Finally, in order to satisfy the demand of the system design, they need to test the system function.For promoting users’experience, there is much improvement in the system. Firstly, the system should load contacts from the phone for the first start, in order to shorten the next start time, the system re-check and sequence the data to store the contacts in the database. Secondly, analyzing and handling the user dialing rules is necessary, such as removing the ineffectual numbers, checking the phone numbers whether fill11numbers or not, then matching the related records or contacts when the users input numbers. Thirdly, the situation of consulting asynchronous message often happens during the communication, so the system not only use handler for consulting but also take measures to some exception in order to improve the system reliability. The application operates stably now and prepares to apply in the Android application market. For those who need vice number business, this application is a good choice.
