Android GPS

I need an application built very simple one initially with the hope of expanding on the initial idea. -Application Function Get GPS Coordinates From Device. Send GPS coordinates to a mysql database using php as the parser. Display GPS Coordinates on screen, this only needs to be simple as we're focusing on the back end. 4 Buttons on Application that can send 4 differant variables to the php parser. -Application will have to meet the condition Condition 1: if(unable to connect to php address that will be hosted remotly){ print "You can not connect to remote server"; } else{ Run the Code } Condition 2: GPS Data will be sent by the press of a button. -Data that will be sent Latitude - will be sent to php and arrive as $_POST['lat']; Longitude - will be sent to php and arrive as $_POST['lng']; Button 1- Variable will be '0' - will be sent to php and arrive as $_POST['btn']; Button 2- Variable will be '1' - will be sent to php and arrive as $_POST['btn']; Button 3- Variable will be '2' - will be sent to php and arrive as $_POST['btn']; Button 4- Variable will be '3' - will be sent to php and arrive as $_POST['btn'];
