PHP Module Java Core Module Android Java Module

Emulator Real Phone

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
