here call 

url url = new url("http://www.server.com/api/v1");             string query = "api_key=q5eicsks027cjut7qhzk&method";              //make connection             urlconnection urlc = url.openconnection();              //use post mode             urlc.setdooutput(true);             urlc.setallowuserinteraction(false);              //send query             printstream ps = new printstream(urlc.getoutputstream());             ps.print(query);             ps.close();              //get result             bufferedreader br = new bufferedreader(new inputstreamreader(urlc                 .getinputstream()));             string l = null;             while ((l=br.readline())!=null) {                 system.out.println(l);             }             br.close();

you need set accept header. 

urlc.addrequestproperty("accept","application/json");

update

your server may not support application/json datatype. can check curl.

curl -x post  -h "accept: application/json" --data 'api_key=q5eicsks027cjut7qhzk&method' http://www.server.com/api/v1
