Parsing JSON response?

Question

I'm having trouble parsing the JSON response for the http post request. What is the issue regarding Json parsing here?

    HttpClient client = new DefaultHttpClient();

    HttpPost post = new HttpPost("url");

    post.addHeader("Content-Type", "application/json");
    HttpResponse response = client.execute(post);

    System.out.println(response.getStatusLine());

    JsonReader reader = new JsonReader(new InputStreamReader(response.getEntity().getContent()));
    Gson gson = new Gson();
    textConv text = gson.fromJson(reader.toString(), textConv.class);
    System.out.println(text.text);

OUTPUT

HTTP/1.1 200 OK

can you print "content" as well? looks like you have [ ] array returned and not a json object — khusrav, Jun 17 '18 at 20:33
Above link is the post request. You can see that it returns a json response — root, Jun 17 '18 at 20:40

@AshvinSharma Yes it does look similar. Just learned that I have to arrange the class to be able to handle the parsed object. Which I clearly haven't. Will try that way and update.. Thank you :) — root, Jun 17 '18 at 20:56

Try making your 'text' field in the object array of strings:

String[] text

Your response has array, and you try to parse it into String object:

{"code": 200, "lang": "en-ru", "text": ["жизнь"]}

Look also here for example of parsing arrays.
