是否可以将数据发送到服务器而不下载响应？

Question

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.

Answer 1

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
