IN PHASE 1…

Communicate with Maps Engine to retrieve current location. (Phase 1)

Register to Coalition to allow communication between 2 PSGs (Phase 1)

FOR PHASE 2 OF PROJECT Integrate Application with Google Maps

Communicate with LASPD to obtain IP address and Port of SOLE-AS server in current location

Allow users to add in their experiences about a particular location / space. Title Name of restaurant / store Ratings Comments Private / Public

Allow users to retrieve experience about the location. Public -> Query the AS server Private -> Retrieve experience from the user itself

SYSTEM DESIGN

Integration with Google Maps

• Allows user to visually see experiences around his location.

• Allows user to set his Name.

• Maps interface is shown when the user launches the application.

SYSTEM DESIGN

Creation of Experience Viewing of ExperienceSpecific fields for each location

SYSTEM DESIGNAS SERVER

SWING based GUI for AS server

Manage general information of the AsServer

Control connection and display all the request in a console

Many future features could be implemented

IMPLEMENTATION DETAILS -GOOGLE MAPS INTERFACE

The MapsDemo class is the main Activity of the

Android application.

Starts service to: Communicate with Map Engine to retrieve

location using BSSID and Map Coordinates Use LASPD to get IP and Port of AS server Communicate with SOLE AS server to retrieve all

experiences in the area Constantly update its location by checking for

changes in BSSID of Wi-Fi Router Update the IP address of the user.

IMPLEMENTATION DETAILS -GOOGLE MAP ACTIVITY The Google Map Activity is responsible for

ensuring that all the information required by the GUI is added to the Intent before it is invoked.

IMPLEMENTATION DETAILS -SOLE-AS SERVER DESIGN

Initial plan to use RMI for communication between PSG and AS server. Problem: RMI library not part of JVM for Android

Hence, we switched back to using traditional socket. Implemented to emulate RMI functionalities

See next slide for diagram.

IMPLEMENTATION DETAILS -SOLE-AS SERVER DESIGN

IMPLEMENTATION DETAILS -MANAGEMENT OF PRIVATE EXPERIENCES

User has to be able to choose if experience he wants to share is private or public.

Public experience – Stored in AS Server (MySQL) Private experience – Stored locally (MySQLite)

Has to get permission from other user

All experiences (public + private) have some data stored on the public SOLE-AS server Private only have ID and Title stored

(short_experience)

See next slide for diagram

IMPLEMENTATION DETAILS -MANAGEMENT OF PRIVATE EXPERIENCES

DIFFICULTIES ENCOUNTERED

Android Emulator cannot accept incoming socket connections. Tried using port redirection but failed

Also, we only had 1 mobile phone to use for testing.

Hence, it was difficult to test communication between Application and Map Engine / Coalition

Solved problem by using personal android phone and writing a PSG simulator on java to simulate PSG on phone

DIFFICULTIES ENCOUNTERED Unfamiliar with details about Android

Programming Eg. Modify Manifest files to access the Internet

Solved by self study and research on internet

Also, the project requires us to use many libraries that have already been created.

Some of them are difficult to use due to lack of documentation and some features were unclear.

Solved by regular meetings with TA, Chen Penghe who clarified all our doubts.

FUTURE DEVELOPMENT

Include XML layout file into the SOLE-AS server such that the GUI Activity can retrieve its layout directly from the server. Provide User interface to allow change in layout

Allow users to take a photo or other multimedia and include it in an experience.
