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=get ResList&LatMax=38&LatMin=37.3&LongMax=-121&LongMin=- 122&str=0&end=2
