  3. Introduction • For this project, I created a Food Phone Application. Some goals were to: • Help users to preview restaurant menus • Search restaurants by food items • Find these things conveniently on the phone • Let’s look at some existing products …

  4. Existing Products • Yelp on Android

  5. Existing Products • UrbanSpoon iPhone Application

  6. Existing Products • iCrave in Android

  7. Feature Comparison

  8. Design • Platform • Architecture • Application Design • Implementation Design

  9. Platform • Android vs. iPhone

  10. Architecture • Client-Server Model • Server (PC) • Client (Phone) • Database

  11. Architecture • Server + Database: • PC • Services • PHP code • Xampp • phpMyAdmin 2.6.2 • Apache 2.0 • Mysql 4.1.20 • Client: • Android Phone • Configuration • Eclipse IDE • JDK 1.5 • Android SDK 1.5

  12. Application Design • Map all possible Outputs to all possible Inputs to define functions: a) = 1), 2), 5)

  13. Activity Relationship • Android Views

  14. Implementation Design • Implementation Model:

  15. Implementation Design • PHP Module • Communicate with the database • Handle upload and download files • Java Core Module • Generate URL to send request to PHP server • Parse the response result from the server • Form Java objects for the Android Java code to use

  16. Implementation Design • Android Java Module • Handle all UI • Phone features • Location • Camera • Internet • Phone storage • Pictures

  17. Testing • PHP Module • Java Core Module • Android Java Module • Emulator • Real Phone

  18. Testing • PHP Module getResList(double LatMax, double LatMin, double LongMax, double LongMin, int str, int end) We can test this function on the PHP server side by using the following URL: http://rome.dynamiccreation.com/~admin22:8888/foodserver.php?function=getResList&LatMax=38&LatMin=37.3&LongMax=-121&LongMin=-122&str=0&end=2

  19. Testing • PHP Module

  20. Testing • Java Core Module

  21. Testing • Android Java Module

  22. Demo

  23. Issues • Emulator Functionality test • Camera • Location • Storage

  24. Issues Stored Procedure Original Design: 4 modules Stored Procedure Module PHP Module Java Core Android Java

  25. Improvement • Image Storage • SD Card? • Memory

  26. Improvement • Prefetching • Assume users want to see the next picture • Prefetching the next picture ahead of time • Shorter user waiting download time for the next picture • Smooth the process
