user8989957:

i tried to made an apps to get result from gmaps API.

I want to use array list to save the result from JSONObject
The log from result_name.toString() return the correct array
But, the log from result_phone.toString() is empty.

I'm confused because the res value is correct. checkEmptyJsonResponse is a class that i created to check whether or not the value for international_phone_number is empty JSON response. It returns either the JSON Value or "Not Available"

String res = checkEmptyJsonResponse(result, "international_phone_number");

In this case, if i put Log to see the value of res, it return the correct value.
It seems that something wrong in result_phone.add(res) but i don't know what

What did i do wrong?

Here is the part of my code that i use

FragmentOne.java

ArrayList result_name = new ArrayList();
ArrayList result_address = new ArrayList();
ArrayList result_placeid = new ArrayList();
ArrayList result_phone = new ArrayList();

public void getLocation(String tipe_instansi){
    final AsyncHttpClient client = new AsyncHttpClient();

    final StringBuilder[] googlePlacesUrl = {new StringBuilder("https://maps.googleapis.com/maps/api/place/nearbysearch/json?")};
    googlePlacesUrl[0].append("location=" + latitude + "," + longitude);
    googlePlacesUrl[0].append("&rankby=prominence");
    googlePlacesUrl[0].append("&radius=" + PROXIMITY_RADIUS);
    googlePlacesUrl[0].append("&type="+tipe_instansi);
    googlePlacesUrl[0].append("&sensor=true");
    googlePlacesUrl[0].append("&key=AIzaSyCtaLQPSPN2SwGM2cr_itZIkWG0sjQJ7uc");
    Log.d("URL : ", googlePlacesUrl[0].toString());


    client.get(googlePlacesUrl[0].toString(), new AsyncHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
            if(responseBody!=null){
                try {
                    JSONObject array = new JSONObject(new String(responseBody));
                    JSONArray result = array.getJSONArray("results");

                    for(int i=0; i                        JSONObject get_result = result.getJSONObject(i);

                        result_name.add(get_result.getString("name"));
                        result_address.add(get_result.getString("vicinity"));
                        result_placeid.add(get_result.getString("place_id"));

                        Log.d("PLACE ID : ", result_placeid.get(i).toString());

                        googlePlacesUrl[0] = new StringBuilder("https://maps.googleapis.com/maps/api/place/details/json?");
                        googlePlacesUrl[0].append("placeid=" + result_placeid.get(i).toString());
                        googlePlacesUrl[0].append("&key=AIzaSyCtaLQPSPN2SwGM2cr_itZIkWG0sjQJ7uc");

                        Log.d("URL2 : ", googlePlacesUrl[0].toString());

                                }
                            }
