Design And Implementation Of Criminal Tracking System Based On Android

At present,with the popularity of mobile Internet,smart devices into homes,can through the android mobile phone application convenient People's Daily life,to improve the work efficiency,has very big effect to the convenience of work,especially the intelligent devices to provide location information and video function,makes the people are free to share information.For the public security system,however,there is a provision to leave the prison to the justice department each year,and each year a small,exceptionally good prisoner is allowed to go home to visit his family.Before the advent of the mobile Internet,every time a criminal went home,a prison guard was required to accompany him to ensure that the criminals were authentic.Such forms are a great waste of human resources.therefore,is designed and implemented in this paper is a kind of personnel tracking system based on android,use of the system,can realize the criminal without accompanying officials at home,also do not need to be in the local public security bureau to authenticate and site validation can be security verification.This is a convenient way to get access to the APP on the offender's own smartphone to complete the task of authentication,location checking,and check-in.This approach is convenient and saves resources.In the design and implementation of this android-based tracking system,this paper mainly studies the reality of the technology of message push,process protection and positioning.This article will contain the following main contents,1.from the background and significance of the research,this paper expounds the background of this topic.This paper introduces the aspects of the design and Realization of the system in the Internet era.2.first layered Android's system architecture was introduced,and then the main components of Android.Next,related technologies such as location technology,message push technology,and process preservation are described.These technologies are important technical support for the implementation of the whole system.3.analysis of the business logic given by the whole personnel tracking system.Starting from functional requirements,the functional modules of the system are described in the use case diagram.It includes login and registration module,sign in module,calendar module,leave module and message sending module.4.according to this functional analysis stage,the design requirements of the whole system have been obtained and the whole system design part has been started.Including the system implementation,the architecture used,the entire system function structure.The client and server side of the whole system is described in the form of class diagrams.5.follow the design phase of the design code to achieve the whole personnel tracking system.From the development environment,detailed implementation of the whole system is introduced.In addition,the whole system is implemented in the way of test cases.
