                        postMethod.setHeader("Accept", "application/json");
                        postMethod.setHeader("Content-type", "application/json");
                        HttpResponse response = httpClient.execute(postMethod);
                     entity = response.getEntity();
                    response_value = EntityUtils.toString(entity).toString();
                       Log.e(TAG, response_value);

Answer 1

You just POST the JSON string to the server and specify the correct header

application/json

The format of the json should be received by the server in the same format as it was sent.

Answer 2

Use toString() to convert your json object to String.

Example :

                String jsonObjString = jsonObject.toString();

                HttpClient client = new DefaultHttpClient();
                HttpPost post = new HttpPost("http://thisisasampleurl.com");
                HttpEntity entity = new ByteArrayEntity(jsonObjectString
                        .getBytes("UTF-8"));
                post.setEntity(entity);
                HttpResponse response = client.execute(post);
                String responseString = EntityUtils.toString(response
                        .getEntity());

You already have the required headers in your code.
