Have a look at TezosJ_SDK/TezosGateway.java (query method).

    MediaType MEDIA_PLAIN_TEXT_JSON = MediaType.parse("application/json");

    String s = "a3...";
    RequestBody body = RequestBody.create(MEDIA_PLAIN_TEXT_JSON, s.getBytes());
    Request request = new Request.Builder()
            .url("http://...")
            .addHeader("Content-Type", "text/plain")
            .post(body)
            .build();


    OkHttpClient client = new OkHttpClient.Builder().build();

    try {
        Response response = client.newCall(request).execute();
        String strResponse = response.body().string();
    } catch ...
