I would like to use an android app to send GPS coordinates using a prepaid sim card. My theory is that if i don't download any response and i only send requests, i won't drain the card of money.
To test this: Is there a way to 1. On android; create a certain type of request that does not expect a return? 2. on the server side; (preferably php -lamp stack) not deliver a response?
I feel like it would be something to do with UDP versus TCP.
Creating a socket connection to your server and writing using UDP protocol will do the trick as Steve explain above Here what i did similiar without responce
InetAddress serverAddr = Inet4Address.getByName("addressIP");
Socket socket = new Socket(serverAddr, SERVERPORT);
socket.getOutputStream().write("your data".getBytes());
Where SERVERPORT stands for 8080,4040 anything depends on your server. I Used this piece of code to communicate with Server
HTTP typically runs over TCP. If you wrote a client server model that uses UDP or some sort of hybrid approach instead, then this could work. While I am by no means an expert, I don't know of any commonly used RESTful applications that run over UDP.
