Chhajed Seha S. Chhajed Seha S. Khivsara B.A. Abstract Beig i the era of Geeratio IV systems ad techology is growig ad chagig at almost every aosecod. Smart Phoe s ad Palmtops are also o exceptio for the same. Everywhere we keep o listeig the word Adroid & Maps which is at its pick of success amogst yougista. Due to rapid growth ad huge chages i Adroid, we decided why ot to desig a applicatio which ca user proe as per their eed. So, we desiged a set of multiple applicatios like Place Markig, Shortest Path Strategy & Weather Predictios for Next 4 days. These applicatios work with co-ordiatio with Google Maps i live eviromet to keep track of the Places ad poits of iterest as per user for future use. Also these applicatios fid the shortest path ad weather predictio for ext four days i degree cetigrade as well as Fahreheit I. INTRODUCTION I recet years the mobile has become the valuable part of the huma beigs. It is ecessary for huma begis to have a powerful device which will provide all the facilities other tha basic facility available i mobile phoes. Adroid provide such fuctioality which eables the developers to desig such applicatios which will make a simple mobile to smart oe. Adroid is built o the ope Liux Kerel. Furthermore, it utilizes a custom virtual machie that has bee desiged to optimize memory ad hardware resources i a mobile eviromet. Adroid is ope source it ca be liberally exteded to icorporate ew cuttig edge techologies as they emerge. The platform will cotiue to evolve as the developer commuity works together to build iovative mobile applicatios. [8] [9] The proposed system is goig to provide the facilities to the users whe user is ewer to ay place through the applicatio amed places directory. Aother applicatio of proposed system is shortest path is goig to provide the service to user by miig the shortest distace betwee source ad destiatio. The last applicatio amed GPS Alarm of proposed system will provide the otificatio to the user of arrival of its specified destiatio while travellig i the form of alarm. II.

III. RELATED WORK As metioed i the previous chapter, applicatio developmet for Adroid mobile phoes is ot ucommo, For example, Voice search, map ruler2 for adroid, Accidet Alarm system. A.Tiahe Zhag proposed voice search applicatio It icludes a techique for improvig the performace of automated voice search services iteded for mobile users accessig these services over a rage of portable devices [4]. Voice search is implemeted as a two stage search procedure where strig cadidates geerated by automatic speech recogitio (ASR) system are re-scored i order to idetify the best matchig etry from a potetially very large applicatio specific database. Limitatios 1) Laguage prouciatio Barrier 2) It is ot helpful for dumb people C. Halvey proposed the average time segmetatio method It uses the average values icrease ad decrease a userspecified rage as the time segmetig positios. However, the user-specified rage is still a difficult defiitio value [6]. Limitatio 2) Less accurate. D. Gozalez proposed method to calculate shortest path It cosiders some evirometal factors that may reflect the ifluece of the velocity of vehicle, ad the these factors are used to build the decisio tree. The velocity of vehicle is evaluated by the curret evirometal situatios [7]. Limitatio 1) Not accurate because of evirometal factor. E. Wag Wei proposed a alarm otificatio for traffic accidets It ca automatically detect a traffic accidet, search for the spot ad the sed the basic iformatio to first aid ceter withi two secods coverig geographical coordiates, the time ad circumstaces i which a traffic accidet takes place [3]. IV. PROPOSED SOLUTION A. Algorithm For Places Directory Display the list of applicatios if (apps = =PD) // PD = Places Directory { Display the list favorites. Select oe of the places. Display all the sub places come uder Selected place. Display iformatio of selected place. B. Hart proposed A*algorithm It is based o a greedy best-first search algorithm. A*algorithm uses a heuristic fuctio to evaluate from startig locatio to destiatio locatio. The heuristic fuctio is divided ito two fuctios: the path-cost fuctio ad the heuristic estimate fuctio [5]. The path-cost fuctio is the cost from startig locatio to the curret locatio ad the heuristic estimate fuctio is the estimatio cost from curret locatio to destiatio locatio. Limitatio 1) Time cosumig. 85

Algorithm for shortest path if (apps = = SP) // SP = Shortest Path { Take Iput from user // (source, destiatio) Cal (source, destiatio) { depedet o automatic speech recogitio, time segmetatio, while those applicatios do ot provide exact iformatio about place which user required ad exact shortest path i terms of distace. After studyig may researches papers ad also addressed may problems but the oe s metioed above are the major issue so the proposed system will try to solve may problems related with speech recogitio, time segmetatio. I order to help the user who is ewer to the city, at travellig time ad to get the commo shortcuts, Places Directory, Smart distace ad weather forecast are oe of the best optios. Source = Distace [Source]+ i1 Distace-Betwee [Source, C i ] 1. Places Directory V. EXPERIMENTAL WORK i1 Ci = Source // Ci = No. of Cities C. Algorithm for Weather forecast else { // apps = Weather Forecast Take iput from user. // i.e. city ad coutry If checkbox is clicked // F, C= temporary variable C= (F-32)*5/9 Else F= C*9/5+32 Display weather iformatio to user. Figure 1 Places Directory Iput This form will provide list of favorites to the user. Accordig to user iput place it will switch to ext form i which user will get the pi poit locatio of that particular locatio o the map. The challege addressed by mobile was the ability to get exact locatio from the specified favorites, fidig the shortest path with faster speed ad otifyig the user about the specified destiatio while travellig. Poited out from the research that may applicatios has bee developed, but some of them 86

CONCLUSION The mai objective of Adroid applicatios usig GPS avigatio is to provide guidelies to the perso who is ewer i the city ad while travellig. As proposed system icludes applicatio Smart distace that provides the shortest way to reach the destiatio so that valuable time of perso gets saved. Aother applicatio amed Places Directory provides the facility to fid out various places earby to the perso that peoples usually eed to visit daily. Agai aother applicatio amed Weather Forecastig provides service i terms of weather iformatio of specified place with pictorial ifo.
