- 3. INTRODUCTION RALLY is based on Google map’s integration and location based services in Android Its working model is gaming concept based on user location The application runs on top of Google maps Tracking user location is important part of this project Player is presented with set of markers These markers can be followed in two differents ways: Automatic and Custom 3
- 4. WHAT IS RALLY? It is team application The team has to join points in order or not depending on the modes they choose All points are located on the Google Maps Each path represents as the joining of points on maps either ordered or unordered All points are selected on the mobile device NOTE: The application can be client/server but for now it is android only 4
- 5. WHY ANDROID ? Android is one of the most used OS for smart phones over 1.4 billion devices running. Its platform is of open system architecture with versatile development and debugging environments. It offers rich graphics systems It supports GPS, video camera, compass, 3d- acceleromrter and provides rich API’s for map based location services. Users can access, control, process Google map and implement location based services at low cost. It follows a software stack architecture . 5
- 6. ANDROID ARCHITECTURE Its basically described by a software stack model : Linux Kernel: android relies on linux kernel for core services such as memory/process management, security and driver model Libraries: include set of C/C++ libraries used by various android system components Android Runtime: provides set of core libraries that provides most of functionality Application Framework: includes all the application in the form of services such as Activity manager, Location manager. Applications: basic core apps on top framework eg. SMS 6

- 8. LOCATION BASED SERVICES (LBS) 8 LBS is software-level service that uses location data to control features. There are two ways to track mobile device’s location: Communication Network (Eg. WiFi) and GPS In our project we used GPS based service to track user location and show it on the Google Map.
- 9. 9 The above components work together to form a whole network that is utilized to find the user location. GPS providers facilitate geo-specific functionality of LBS including map information, visualization and directory services.
- 10. ANDROID LOCATION API Android has the location package that contains all the functions used for getting geo location of user. Functionalities and classes that we have used in our project are represented in this table. Class Name Functionality Location It is a data class representing a geographical location LocationManager Class provides access to the system location service LocationProvider Abstract super class for location providers LatLng Class describes location in form of longitude and latitude GpsStatus Represent current state of GPS engine GpsSatellite Represents current state of GPS satellite 10
- 11. GOOGLE MAPS ANDROID API It is a mapping service developed by Google. It offers satellite imagery, street maps, 360° panoramic views of streets (Street View), real-time traffic conditions (Google Traffic), and route planning Maps are represented in the API by GoogleMap and MapFragments API automatically handles access to Google Maps servers Also facilitates data downloading, map display, and response to map gestures 11
- 12. OBJECTS OF MAPS API Icons anchored to specific positions on the map (Markers) Sets of line segments (Polylines). Enclosed segments (Polygons) Maps API KEY is needed by the application to connect with Google Maps API You can put restrictions for access on the API key Getting an API key is simple process by creating it through Google’s developer console 12
- 13. ANDROID RALLY Project “Rally” is based on the location based gaming concept like “Pokemon Go” •It includes the Google Maps to show user location •And GPS to track the changing user’s location •The application includes two modes •Automatic mode: markers and path both are given to follow •Custom mode: only markers are given 13

- 15. THE MAIN SCREEN OF RALLY 15
- 16. ADMIN FUNCTIONALITY The Admin is responsible for selecting the positions for the Rally After the selection these points are send to Automatic and Custom activities The points are send in ordered manner to Automatic activity Points are send unordered manner to Custom Activity 16
- 17. ADMIN SCREEN 17
- 18. AUTOMATIC FUNCTIONALITY 18 The selected points appear with the path that the user must follow in the rally In this mode user have to directly follow the points given by the Admin Start represented by green color Destination represented by blue colour
- 19. CUSTOM FUNCTIONALITY Here the points selected by the Admin are shown But without the path to follow The user can follow any path he wants But all points should be traversed 19
- 20. CONCLUSION Our project is a demonstration of Google Maps Our application satisfies the objective of our project This application though very simple in working but can be engaging and provides you with a different aspect of looking at the android games. FUTURE SCOPE This application can be moved to client/server application 20
