google cloud translation API using okhttp3

Question

I am developing an android app where I have to convert user's speech to text(using google cloud speech API) and then that text into another language (using google cloud translation API).

Now,

I have successfully converted user's speech into text but the issue is while converting that text into another language I get nothing in the response body. When I send request to cloud translation API using my browser (eg, Google Chrome) then it returns as expected (shown below).

The request that I sent: https://translation.googleapis.com/language/translate/v2?target=es&key=MY_API_KEY&q=this%20is%20the%20text%20which%20is%20need%20to%20be%20translated

{
"data": {
"translations": [
   {
    "translatedText": "este es el texto que debe ser traducido",
    "detectedSourceLanguage": "en"
   }
  ]
 }
}

But the problem is when I send the same request from my app using OkHttp3 then it returns following response

Response{protocol=h2, code=200, message=, url=https://translation.googleapis.com/language/translate/v2?target=es&key=MY_API_KEY&q=this%20is%20the%20text%20which%20is%20need%20to%20be%20translated}

body = OkHttp-Selected-Protocol: h2 content-type: application/json; charset=UTF-8 vary: Origin vary: X-Origin vary: Referer date: Sun, 30 Sep 2018 08:27:40 GMT server: ESF cache-control: private x-xss-protection: 1; mode=block x-frame-options: SAMEORIGIN x-content-type-options: nosniff alt-svc: quic=":443"; ma=2592000; v="44,43,39,35" OkHttp-Sent-Millis: 1538296059111 OkHttp-Received-Millis: 1538296060590

okhttp3 dependency is shown below

compile 'com.squareup.okhttp3:okhttp:3.11.0'

My code for translating text is shown below

private void getTranslation(String url) {
    OkHttpClient client = new OkHttpClient();

        Request request = new Request.Builder()
                .url(url)
                .build();

        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Request request, IOException e) {
                Toast.makeText(SpeechService.this, e.getMessage(), Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onResponse(Response response) throws IOException {
                String res = response.body().toString();
                String mess = response.message(); //gets nothing as message response

            }
        });
    }

Note: Even I receive the code 200 but still there is nothing in the message of the response

response.message() is the HTTP status message, like "OK" from 200 OK. You should also check response.code() which will be numeric. response.body.toString() is for debugging

  @Override public String toString() {
    return "Response{protocol="
        + protocol
        + ", code="
        + code
        + ", message="
        + message
        + ", url="
        + request.url()
        + '}';
  }

You want

String res = response.body().string()
