HttpRequest request = HttpRequest.post("http://localhost/").header(HttpRequest.HEADER_CONTENT_TYPE, HttpRequest.CONTENT_TYPE_JSON).send("{\n" +
                "    \"app_id\" : \"0.1.10\",\n" +
                "    \"channel_tag\" : \"production\",\n" +
                "    \"device\" : {\n" +
                "        \"snapshot\" : \"0.1.10\",\n" +
                "        \"binary_version\" : \"0.1.10\",\n" +
                "        \"platform\" : \"android\"\n" +
                "    }\n" +
                "\n" +
                "}");
