Iteration 1 Presentation

2. Overview This application uses a client – server architecture.
This application uses GPS (Google Maps Functionality) to show the user’s location, and their friend’s location by marking them with icons.

3. Overview of Database
The database contains all the usernames and passwords for each of the application’s users.
The database also contains the friends list for each of the users.
It also allows the user to locate a specific friend.

4. Requirements GPS (Google Maps Functionality) Database Friend Finder
User’s Location, Friend’s location, Icons
Database
Latitudes and Longitudes
Account Framework with Registration Validation
Password
Friends List
Friend Finder
Search by friend’s name and get results

5. Completion of Version 1
This application shows the user’s location on a map by panning to that location as soon as they log in.
The user can find an existing friend’s location and have the map pan to that location.

16. How It All Works
System Architecture

17. Source Code Packages Client Server Authentication Database Messaging
Users
Authentication
Database
Messaging
Users
Client Only
Maps
Graphical User Interface (GUI)

18. Messaging Client Server Contains ClientMessenger
Responsible for connecting to Server on Maxwell over TCP Socket
Transmits Message to Server
Receives response, decodes, passes to proper Client-Side component
Contains ServerMessenger
Listens on Maxwell’s port:35018
Receives Messages, decodes, passes to proper Server-side Component
After Processing occurs, sends response to client
Closes TCP Socket

19. Database Client Server Functions wrap SQL queries in Messages
Pass messages to ClientMessenger
Receive response
Receives decoded command from ServerMessenger
Corresponding functions wrap SQL commands
Passes results to ServerMessenger to return to ClientMessenger

21. Users
Client
Server
Functions wrap up corresponding Messages to the server
Makes User manipulation easy
Hides back end Server/DB communication
Handles User Manipulation
Adding/Removing Friends
Updating Location
UserManager wraps DatabaseConnector to provide a DB Layer

22. Authentication Client Server Wrapper around Database Manager
Message to Server containing Credentials
Authenticates User on Client
Passed credentials from Messenger
Authenticates User
Passes SUCCESS/FAILURE message to Messenger to return to client

23. GUI and Maps
GUI
Maps
Contains code to transition from Activity to Activity
Leverages Google Maps API
Uses MapActivity and MapView
Responsible for plotting User pushpins
Communicates with Android GPS Provider to keep User’s position current

24. System Architecture

25. Our Code in Action
DEMONSTRATION

26. Looking Into The Future…
Plans for Iteration 2

27. Functionalities To Be Implemented
Improve “Update” Feature
Enhance GUI and Visual Appearance
Implement User Registration
Search for Friends and Add Friends
Allow the User to Log Out

28. Improve Update
The Update feature causes the system to keep a current, accurate account of where each User is located.
Purpose: whenever a User moves, his or her icon will move along the map accordingly on all of his or her Friends’ phones

29. Enhance GUI Screens to be created: Settings Search for Friends
Add Friends
Screens to be Modified
Friends List and Map
Registration

30. Creation: Settings Change Size of Pushpin Default Zoom Invisibility
Change Icon

31. Creation: Search Search for a given User (by Username)
Add a search result to the User’s Friend’s List

32. Creation:
Add Friends
Post-Search – add a “found” Friend to the User’s Friend’s List
Once added, the Friend appears on the User’s Map

33. Modify: Friends List And Map
Implement a uniform visual structure for buttons and layout
Line up all components

34. Modify: Registration Add “Create Account” button
Implement the same uniform structure

35. Enable Registration Allow Users to create accounts
Creation options include the following:
Selecting Username
Selecting Password
Selecting Map Icon

36. Enable Friend Searching
Using the newly-created GUI, Users will be able to search for other registered Users
Clicking the “Add” button next to one of the listed results allows the User to add the selected person to his or her Friends List

37. Log Out The User is logged out of the Application
Returns the User to Log In screen
