Calendar Design And Implementation Of APP Multiple-run Function Based On Android Customized Vision System

Smart phones become more and more popular with the rapid development of mobile Internet technology.According to the latest released statistic data from the famous American data statistics company IDC shown that the global volume of sales of the smart phones is more than 1.47 billion in 2016.Android system has become the most popular mobile device platform and the application development based on Android system has broad prospects.For smart phones,the overall system software interface is directly related to the user experience.With the higher and higher requirements of system software user interface(UI),the research and design of UI has also become a research hotspot.In order to make the software interface of mobile system unified,the style and theme of system software need to be consistent.However,Android system UI component cannot achieve the effect,so the Android system UI component customization and redevelopment are significant.This thesis develops the Android customized Vision UI component system based on the customized requirements.This is the first part of the thesis.Calendar application is an indispensable software for Android mobile phone system,which provides great convenience for users to view time and date,create new schedule,set reminders and so on.This thesis studies the design and development of the new functions of calendar based on Android customized Vision system and the new functions mainly include the Sina subscription,weather show,birthday reminder,festival reminder and holiday automatic update in the calendar.The realization of these functions can make the calendar application more comprehensive.It can facilitate the work and life of the people.This is the second part of the thesis.The development and realization of APP Multiple-run is the third part of this thesis.The startup mode of Android system application is different from the Windows system where the application can multiply run.However,the traditional Android system cannot start the same two applications at the same time.Firstly,this thesis analyzes the limitations of APP Multiple-run function from the view of Android APP startup process.In the following,we design and realize the APP Multiple-run function in Android system by setting different instanceld for the APP and its clone body in the Android application layer and modifying the application startup process in the Android application framework layer.This thesis first develops the Android customized Vision system.Then,we design and develop the calendar new functions based on the Vision system.Finally,the high-level function of the joint development of the APP Multiple-run application layer and the framework layer in Android system is achieved.It is convenient for the users to get a better user experience.
