1 3rd Iteratioal Coferece o Materials Egieerig, Maufacturig Techology ad Cotrol (ICMEMTC 2016) Ati-addictio System Developmet Based o Adroid Smartphoe Xiafu Pa Haia Vocatioal College of Political Sciece ad Law, Haikou Haia, , Chia Keywords: Smartphoe, Adroid system, Ati-addictio system, Addictio idex, Desig Abstract. Although the smartphoe brigs people more coveiece ad etertaimet, may troubles are also caused, such as smartphoe addictio problem. The smartphoe gives rise to severe impacts o the life, study ad work of users with poor self-cotrol ability. Especially for those uder age, smartphoe addictio has become a global issue ad receives extesive attetio from the idustry. This paper aalyzes addictio idex calculatio method of smartphoe Adroid system ad ati-addictio system desig, ad displays the implemetatio of system fuctios. Itroductio Adroid system is oe of the most extesive ad the most mature operatig systems with the best stability. With strog ope-source opeess, Adroid system ca provide free ad complete source code dowloadig program for users. As well, it ows strog customizatio fuctio ad brigs diversified ad rich experiece for users' differet demad. Sice Adroid system has overall structure module with good stability ad uiformity, it also offers solid guaratee for good desig ad trasplatatio of ati-addictio system. Specific calculatio method of smartphoe addictio idexes Prior to ati-addictio system desig for the smartphoe, a set of accurate ad ratioal addictio idex calculatio method should be provided. All iformatio ivolved i addictio idexes should be fully quatified, which is beeficial to subsequet calculatio accuracy. This paper gives the specific calculatio method accordig to relevat cocept of addictio idexes. Calculatio of uit miute addictio value Huma addictio to the smartphoe is maily judged with the time. For example, oe's addictio degree i a time bucket depeds o the proportio of game playig time i the total time. For the same game, the hazard degree for people is differet uder differet situatios. For istace, the game is played i the followig three coditios: Firstly, the hazard of smartphoe etwork game is larger tha that of puzzle game. Its hazard ca be expressed with software hazard coefficiet. Secodly, playig game i the rest time has larger hazard tha playig game i leisure time. Its hazard ca be expressed with time-poit hazard coefficiet. Thirdly, whe oe cotiues to plat game, the hazard i the last miute is larger tha that i the first miute. Its hazard ca be expressed with duratio hazard coefficiet. Uit miute addictio value reflects the above three situatios. It ca correct the hazard of smartphoe o people to every miute, ad every miute correspods to a uit miute addictio value. Besides, uit miute addictio value also idirectly embodies two idexes: addictio severity ad software addictio degree. Mathematical calculatio formula of uit miute addictio value is as follows: At = st pt lt Where, At represets uit addictio value of the tth miute i the specified time bucket; s t refers to software hazard coefficiet of game software at the tth miute; p t represets hazard coefficiet at the tth miute; l t is duratio hazard coefficiet at the tth miute The authors - Published by Atlatis Press 19

2 Calculatio of software easy addictio idex Software easy addictio idex is very complex. Adroid system platform ows umerous kids of software, ad it is very difficult for people to kow which software will form software addictio. For istace, if oe's WeChat operatio duratio is 60mi, uit miute addictio value withi the 60mi will accumulate cotiuously ad fially form WeChat addictio accumulative value. At preset, WeChat addictio has o cotigecy. WeChat has becomes a kid of major software which the majority of people will be addicted to. Thus, this paper calculates software easy addictio idexes based o movig average method. The thought of movig average method is to predict ad calculate future iformatio through the latest group of measured data. Such method ca furthest reduce radom fluctuatio geerated i the predictio process. Sice the recet data are adopted, the referece ad correlatio are also guarateed. This paper applies this method to achieve liear icrease judgmet method of differet data ad differet weight. So, easiest addictio software A is take for example. Its easy addictio idex E A should be: E w B + w B + + w B )( w + w + + w ) A = ( 1 A1 2 A2 A / 1 2 Where, meas that the data rage is the past days; B S is accumulative addictio value of Software A days ago; w refers to relevacy weight value days ago. Whe is closer, its relevacy weight value is larger. To calculate addictio idexes, accumulative addictio value B S of the software should be settled oce per day, ad ew data should be added cotiuously to esure accuracy ad istataeity of addictio idexes. Calculatio of addictio severity idex Addictio severity idex is calculated o the basis of software easy addictio idex. Addictio severity idex weighs addictio depedece degree of smartphoe users o a kid of software. It completely starts from users, divides addictio severity for users ad the divides ati-addictio hadlig grade accordig to correspodig grade. Here, we assume addictio severity idex is X, each uit miute addictio value withi the specified time is superposed to gai dt X = A = st pt t= 1 t e t= 1 Where, represets the total time cosumed of each kid of smartphoe software withi a time bucket i oe day, ad the uit is miute [1]. Ati-addictio system desig Aalysis of overall system architecture Ati-addictio system of Adroid smartphoe icludes applicatio layer ad framework layer. This system ivolves applicatio developmet, modificatio ad expasio etc. the applicatio layer ca achieve basic fuctios of ati-addictio. It is actually divided ito ati-addictio maagemet ad ati-addictio service. Ati-addictio maagemet cotais user iteractive Activity iterface through which smartphoe users ca check ati-addictio iformatio of each kid of software ad modify ati-addictio stadard aytime. Ati-addictio service achieves backstage service through Adroid Service module which moitors operatig state of each kid of Smartphoe software i all weathers, ows the fuctios of moitorig user-defied broadcast ad specific broadcast ad ca hadle most addictio ispectio tasks. The framework layer is a mai core part of ati-addictio system fuctio extesio. It is resposible for operatig remote moitorig maagemet module ad protectio module, protectig ad modifyig the origial iterface i Adroid system framework layer so as to make sure ati-addictio applicatio program operates safely ad stably. Whe ay abormity occurs i ati-addictio applicatio operatio program, the framework layer will start self-recovery fuctio, 20

Aalysis of framework layer extesio fuctio Framework layer extesio of Adroid system ivolves modificatio ad extesio which are also the difficulties i developmet ad desig of ati-addictio system. The desig difficulty is caused by complexity of Adroid system framework layer. This paper displays mutual relatios of modificatio ad extesio modules i structure compositio i the framework layer through the structure chart, ad the relatioship betwee them ad exteral role, as show i Fig.1. Fig.1. Schematic diagram of framework layer extesio relatio i Adroid ati-addictio system As show i Fig.1, framework layer extesio module is i the ati-addictio system of Adroid system, ad it icludes three parts: operatio protectio, bottom-layer supervisio ad remote SMS cotrol. Bottom-layer supervisio also cotais remote supervisio ad abormal supervisio, while remote SMS cotrol ivolves two liks: SMS moitorig ad sedig. Next, this paper maily itroduces three compoets of framework layer extesio module. Operatio protectio Operatio protectio is the first barrier of framework layer for ati-addictio i the applicatio layer, smartphoe users may use task maager to operate it as required by the system or apply third-party smartphoe steward software for operatio protectio. Such operatio ca itervee i ormal operatio of ati-addictio applicatio. For istace, it ca achieve forced closure ad deletio of data, eve force to uload some iheret smartphoe software ad realize forced prohibitio of operatio. Bottom-layer supervisio It is the kerel module of framework layer extesio itesificatio fuctio. It ca achieve abormal supervisio ad remote supervisio. The origial itetio of abormity supervisio desig is to supplemet the fuctios of operatio protectio module, but i fact its protectio thought is differet from operatio protectio. It is ot beforehad protectio, but post detectio protectio. It ca automatically achieve system abormity remediatio ad recovery. Whe recovery fails, it will immediately iform remote supervisor, which is called paret iformig fuctio of ati-addictio system. Meawhile, it ca receive remote cotrol iformatio sed by remote moitorig system, the modify some ati-addictio maagemet preset data accordig to iformatio cotet ad achieve complete remote smartphoe maagemet fuctio. Remote SMS cotrol Remote SMS cotrol is specially used to achieve remote supervisio. It cotais SMS moitorig ad SMS sedig ad achieves remote cotrol ad remote moitorig of Adroid system. To meet users' differet demad, it also sets prior moitorig level, classifies differet SNS, achieves aalysis 21

4 of SMS cotets from diverse perspectives ad fially iforms remote supervisio fuctio to execute correspodig istructios, such as SMS iterceptio. Database desig aalysis To desig Adroid system database, SQLite database with good compatibility may be adopted. It ca realize local preservatio ad maagemet of data, weighs redudat iformatio i the database as eeded, improve database operatio efficiecy ad fially achieve database desig fuctio. Database desig maily icludes the followig 4 parts. Firstly, applicatio iformatio table ca record basic iformatio of istalled software i Adroid system, icludig recordig attribute iformatio about ati-addictio system. It is also deemed as the fudametal ad core data stadard of ati-addictio system. Secodly, duratio maagemet table maages data maually. Its ati-addictio system is directly istalled i data maagemet software uder paret fuctio ad ca achieve digital judgmet of addictio stadards. I other words, duratio maagemet table ca save all idex data set i the supervisio module. Thirdly, operatio record sheet ca operate a applicatio i a time bucket, maage addictio accumulatio degree, software easy addictio idex ad addictio severity idex, ad offer data calculatio for the three idexes. Fourthly, system log sheet is maily resposible for savig all system evets i the system, such as ispectio of a time poit. If severe addictio is discovered, addictio hadlig should cotiue to be executed util abormal behavior is recovered. It presets itelligece, ad humaizatio idea, ad it is the most importat backstage techology support i ati-addictio system [2]. Aalysis of applicatio ad implemetatio of ati-addictio system Eviromet setup implemetatio of ati-addictio system Eviromet setup implemetatio of ati-addictio system of Adroid smartphoe maily experieces 4 steps. Step 1, Adroid source code dowloadig. Source code dowloadig should be coducted accordig to experimet platform ad correspodig versio. For example, o Google exus platform, protogeetic Adroid system offered officially should be dowloaded. Other smartphoes should select correspodig source code provided by third-party ROM. Step 2, source code compilatio operatio. Before the source code is compiled, correspodig compilatio tool ad depedece package should be dowloaded first. I the compilatio process, it is ecessary to take ito accout of potetial errors, such as whether the compilatio tool ad depedece package are cosistet with source code versio used by curret Adroid. I source code compilatio process, make istructio should be applied to implemet global compilatio. The, mmm istructio should be applied to implemet module compilatio. For istace, whe Activity Maager Service path is modified i the system, the ew path is updated i the ew system after the modificatio to achieve the purpose of system modificatio ad customizatio. Step 3, Eclipse importig debuggig. Because Adroid source code egieerig compilatio is quite complex ad huge, uiform maagemet software of a code should be prepared, such as Source Isight code reader. This code reader ows Eclipse system which supports correspodig Adroid system. After Adroid system is fiely tured, Adroid source code ca be completely imported i Eclipse. After this operatio, complex source code readig efficiecy of the system will improve a lot. Step 4, smartphoe refreshig. The modified ad exteded system is refreshed i smartphoe system to detect actual applicatio feasibility ad security of ati-addictio system. It cotais the ifluece of ati-addictio system o smartphoe property ad power cosumptio, ad whether remote moitorig fuctio ca operate ormally. After all relevat source codes are compiled, they 22

Summary This paper discusses the hot issue - smartphoe addictio from specific calculatio of ati-addictio idex ad ati-addictio system desig. Ati-addictio system desig based o Adroid smartphoe ca oly prohibit addictio behavior objectively ad play the assistat maagemet role. More importatly, smartphoe users should ehace their subjective cosciousess ad establish correct value attitude to the use of smartphoe software i order to fudametally solve smartphoe addictio problem.
