I think you can refer to my following sample code, then use its logic for your app:

private class POSTRequest extends AsyncTask<Void, Void, String> {

        @Override
        protected String doInBackground(Void... voids) {
            String address = "http://192.16.1.100:24780/api/token";
            HttpURLConnection urlConnection;
            String requestBody;
            Uri.Builder builder = new Uri.Builder();
            Map<String, String> stringMap = new HashMap<>();
            stringMap.put("grant_type", "password");
            stringMap.put("username", "bnk");
            stringMap.put("password", "bnkpwd");

            Iterator entries = stringMap.entrySet().iterator();
            while (entries.hasNext()) {
                Map.Entry entry = (Map.Entry) entries.next();
                builder.appendQueryParameter(entry.getKey().toString(), entry.getValue().toString());
                entries.remove();
            }
            requestBody = builder.build().getEncodedQuery();

            try {
                URL url = new URL(address);
                urlConnection = (HttpURLConnection) url.openConnection();
                urlConnection.setDoInput(true);
                urlConnection.setDoOutput(true);
                // urlConnection.setRequestMethod("POST");
                urlConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
                OutputStream outputStream = new BufferedOutputStream(urlConnection.getOutputStream());
                BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "utf-8"));
                writer.write(requestBody);
                writer.flush();
                writer.close();
                outputStream.close();

                JSONObject jsonObject = new JSONObject();
                InputStream inputStream;
                // get stream
                if (urlConnection.getResponseCode() < HttpURLConnection.HTTP_BAD_REQUEST) {
                    inputStream = urlConnection.getInputStream();
                } else {
                    inputStream = urlConnection.getErrorStream();
                }
                // parse stream
                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
                String temp, response = "";
                while ((temp = bufferedReader.readLine()) != null) {
                    response += temp;
                }
                // put into JSONObject
                jsonObject.put("Content", response);
                jsonObject.put("Message", urlConnection.getResponseMessage());
                jsonObject.put("Length", urlConnection.getContentLength());
                jsonObject.put("Type", urlConnection.getContentType());

                return jsonObject.toString();
            } catch (IOException | JSONException e) {
                return e.toString();
            }
        }

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            Log.i(LOG_TAG, "POST\n" + result);
        }
    }

UPDATE:

With your PHP code, you can try the following update:

...
                JSONObject json = new JSONObject();
                json.put("key1", "sample value...");
                requestBody = json.toString();
                URL url = new URL(address);
                urlConnection = (HttpURLConnection) url.openConnection();
                urlConnection.setDoInput(true);
                urlConnection.setDoOutput(true);
                urlConnection.setRequestProperty("Content-Type", "application/json");
                OutputStream outputStream = new BufferedOutputStream(urlConnection.getOutputStream());
                BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, "utf-8"));
                writer.write(requestBody);
                writer.flush();
                writer.close();
                outputStream.close();
...
