I have a contactList = new ArrayList<>(); where I store information in this format: "name", value_for_name.

I populate my contactList inside this function:

protected Void doInBackground(Void... arg0) {
            HttpHandler sh = new HttpHandler();

            // Making a request to url and getting response
            String jsonStr = sh.makeServiceCall(url);

            Log.e(TAG, "Response from url: " + jsonStr);

            if (jsonStr != null) {
                try {
                    JSONObject jsonObj = new JSONObject(jsonStr);

                    // Getting JSON Array node
                    JSONArray contacts = jsonObj.getJSONArray("results");

                    // looping through All Results
                    for (int i = 0; i < contacts.length(); i++) {
                        JSONObject c = contacts.getJSONObject(i);

                        String icon = c.getString("icon");
                        String id = c.getString("id");
                        String name = c.getString("name");

                        // tmp hash map for single contact
                        HashMap<String, String> contact = new HashMap<>();

                        // adding each child node to HashMap key => value
                        // contact.put("id", id);
                        contact.put("name", name);
                        // contact.put("email", icon);

                        // adding contact to contact list

                } catch (final JSONException e) {
                    Log.e(TAG, "Json parsing error: " + e.getMessage());
                    runOnUiThread(new Runnable() {
                        public void run() {
                                    "Json parsing error: " + e.getMessage(),

            } else {
                Log.e(TAG, "Couldn't get json from server.");
                runOnUiThread(new Runnable() {
                    public void run() {
                                "Couldn't get json from server. Check LogCat for possible errors!",


            return null;

The problem is that when I try to print a value:


The output is in this format: {name="Foo"}

I only want to print Foo I tried also with:

but I always get the whole string: {name="Foo"}

Can you help me, please? Do I really need to parse the string?
