Detect age of network need for Google Maps Geolocation API

Question

I m creating an app using Google Maps Geolocation API that will get the location of user from Network. Google Maps Geolocation API have some attribute to send in url to get the proper output from Google. My Problem is

1. Cell tower objects - age for reference yu can check here Cell tower objects

2. WiFi access point objects - age , channel , signalToNoiseRatio for reference you can check here WiFi access point object

i tried TelePhonyManager and Wifi ScaneResult(), but do not able to get these value

if someone know or access Google Maps Geolocation API, Please make suggestion so i will pass these value into Google Map API to get best Result

waiting for response thanks

You can use AsyncTask to do the network request.

Sample Code:

  private class GetGeolocationTask extends AsyncTask<Object, Void, String> {

        @Override
        protected String doInBackground(Object... arg0) {
            InputStream inputStream = null;
            String result = "";

            try {
                // 1. create HttpClient
                HttpClient httpclient = new DefaultHttpClient();

                // 2. make POST request to the given URL
                HttpPost httpPost = new HttpPost("https://www.googleapis.com/geolocation/v1/geolocate?key=YOUR_API_KEY");

                String json = "";

                // 3. build jsonObject
                JSONObject jsonObject = new JSONObject();
                jsonObject.accumulate("homeMobileCountryCode", 310);
                jsonObject.accumulate("homeMobileNetworkCode", 410);
                jsonObject.accumulate("radioType", "gsm");
                jsonObject.accumulate("carrier", "vodafone");

                JSONArray cellTowersArray = new JSONArray();
                JSONObject cellTowerObject = new JSONObject();
                cellTowerObject.accumulate("cellId", 42);
                cellTowerObject.accumulate("locationAreaCode", 415);
                cellTowerObject.accumulate("mobileCountryCode", 310);
                cellTowerObject.accumulate("mobileNetworkCode", 410);
                cellTowerObject.accumulate("age", 0);
                cellTowerObject.accumulate("signalStrength", -60);
                cellTowerObject.accumulate("timingAdvance", 15);
                cellTowersArray.put(cellTowerObject);
                jsonObject.accumulate("cellTowers", cellTowersArray);

                JSONArray wifiAccessPointsArray = new JSONArray();
                JSONObject wifiAccessPointObject = new JSONObject();
                wifiAccessPointObject.accumulate("macAddress", "01:23:45:67:89:AB");
                wifiAccessPointObject.accumulate("age", 0);
                wifiAccessPointObject.accumulate("channel", 11);
                wifiAccessPointObject.accumulate("signalToNoiseRatio", 40);
                wifiAccessPointsArray.put(wifiAccessPointObject);
                jsonObject.accumulate("wifiAccessPoints", wifiAccessPointsArray);

                // 4. convert JSONObject to JSON to String
                json = jsonObject.toString();


                // 5. set json to StringEntity
                StringEntity se = new StringEntity(json);

                // 6. set httpPost Entity
                httpPost.setEntity(se);

                // 7. Set some headers to inform server about the type of the content
                httpPost.setHeader("Accept", "application/json");
                httpPost.setHeader("Content-type", "application/json");

                // 8. Execute POST request to the given URL
                HttpResponse httpResponse = httpclient.execute(httpPost);

                // 9. receive response as inputStream
                inputStream = httpResponse.getEntity().getContent();

                // 10. convert inputstream to string
                if(inputStream != null)
                    result = convertInputStreamToString(inputStream);
                else
                    result = "Did not work";
            }
            catch (MalformedURLException e) {
                logException(e);
            }
            catch (IOException e) {
                logException(e);
            }
            catch (Exception e) {
                logException(e);
            }

            return result;
        }

        @Override
        protected void onPostExecute(String result) {
            Toast.makeText(YourActivity.this, result, Toast.LENGTH_LONG).show();
        }
    }

    private static String convertInputStreamToString(InputStream inputStream) throws IOException{
          BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
          String line = "";
          String result = "";
          while((line = bufferedReader.readLine()) != null)
              result += line;

          inputStream.close();
          return result;
    }   

You can call this AsyncTask in your activity like this:

GetGeolocationTask getBlogPostsTask = new GetGeolocationTask();
getGeolocationTask.execute(); 

You can also read this tutorial for detailed information about how to put JSON in request body.

Or, you can use Google Volley library to do your network request, sample request can be found in this Stackoverflow answer.
