I hope you managed to obtain the json data from the json string.

Well I think this will be of help

try {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
    .url(urls[0])
    .build();
Response responses = null;

try {
    responses = client.newCall(request).execute();
} catch (IOException e) {
    e.printStackTrace();
}   

String jsonData = responses.body().string();

JSONObject Jobject = new JSONObject(jsonData);
JSONArray Jarray = Jobject.getJSONArray("employees");

//define the strings that will temporary store the data
String fname,lname;

//get the length of the json array
int limit = Jarray.length()

//datastore array of size limit
String dataStore[] = new String[limit];

for (int i = 0; i < limit; i++) {
    JSONObject object     = Jarray.getJSONObject(i);

    fname = object.getString("firstName");
    lname = object.getString("lastName");

    Log.d("JSON DATA", fname + " ## " + lname);

    //store the data into the array
    dataStore[i] = fname + " ## " + lname;
}

//prove that the data was stored in the array      
 for (String content ; dataStore ) {
        Log.d("ARRAY CONTENT", content);
    }

Remember to use AsyncTask or SyncAdapter(IntentService), to prevent getting a NetworkOnMainThreadException

Also import the okhttp library in your build.gradle

compile 'com.squareup.okhttp:okhttp:2.4.0'

Below code is for getting data from online server using GET method and okHTTP library for android kotlin     Log e  Main  response body   string     in above line    is the thing using which you can get the json from response body  val client   OkHttpClient               val request  Request   Request Builder                    get                    url  http   172 16 10 126 8789 test path jsonpage                    addHeader                          addHeader                          build               client newCall request  enqueue object   Callback                   override fun onFailure call  Call  e  IOException                           Handle this                     Log e  Main   Try again latter                                         override fun onResponse call  Call  response  Response                           Handle this                     Log e  Main  response body   string

As I observed in my code  If once the value is fetched of body from Response  its become blank   String str   response body   string         response      String str1    response body   string        BLANK   So I believe after fetching once the value from body  it become empty   Suggestion   Store it in String  that can be used many time
