Abstract Abstract This paper mainly describes the design of a Data Control App for Androidcell phone .In recent years, with the rapid development of the smartphone industry,the penetration of smartphone is also gradually increased, which makes theservices carried out around smartphone also arises fastly. Which, due to thedemand of the network functions, M obile Internet services has become one ofthe mainly services that smartphone users use . The connection betweencellphones and M obile Internet connection is bound to bring traffic, and th enthe Internet fee has came. However, most of the applications designed for smartphones developed has network functions, and some developers may let theapplication connectting to the Internet in the background with out noticingthe users,which can result in the user's Internet fee increas ing and bringthem unnecessary costs.The Data Control App described in this paper is developed in Javalanguage , by a software named Eclipse .Th is application can check all theapplications ’ data record by reading the phone ’ s network data. So it willbe convinent for users to understand their cellphone ’ s flow datasituation,and making a right distribution of their data traffic. Also,theywill now how to deal with those applications in their pohnes,keeping them orjust deleting them.
