You can do that fairly easy with Gson [LINK] and here nice a [this video] Here is a little code example public void getFromServer(){ final String url =YOUR URL HERE final ArrayList<ElementEntity> arrayOfCities = new ArrayList<>(); // prepare the Request final JsonArrayRequest getRequest = new JsonArrayRequest(Request.Method.GET,url,null, new Response.Listener<JSONArray>() { @Override public void onResponse(JSONArray response) { // display response Log.d("Response", response.toString()); for(int i = 0; i< response.length();i++){ try { JSONObject jresponse = response.getJSONObject(i); YourObject yourObject = gson.fromJson(jresponse.toString(),YourObject .class); arrayOfYourObject.add(yourObject); }

Network requests with Android should be done with a library, such as Retrofit or Volley. If you are new to Android and/or looking for a quick solution to your login, I suggest trying Volley as it takes less experience to set up. Here is a good resource to learn about Volley [this video] . Another good option, and the most widely adopted solution as of current is Retrofit. If you are doing anything more than a few simple network calls in your app, I strongly suggest learning about Retrofit [LINK] . It takes a bit more Android knowledge in my opinion, but it is a more elegant solution and worth the learning. You will have to learn to make a POST request to your API using either of these libraries,
