android - GET-request with Loopj

Question

I need to make GET-request to a url consisting JSON-data and try to use Loopj library, but it returnes nothing. I tried to find examples on the Internet but they turned out, maybe, to be obsolete (onSuccess method had different parameters). I tried to adapt my code to that example and what I got:

String AllData=""; AsyncHttpClient client = new AsyncHttpClient();
    client.get("wantedUrl", new AsyncHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
            for (byte aResponseBody : responseBody) {
                AllData += aResponseBody;
            }

        }
        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
            Toast.makeText(getApplicationContext(),"We got an error",Toast.LENGTH_SHORT).show();
        }
    });

"wantedUrl" is the url with json, but "AllData" remains empty. How to fix it?

You're getting AsyncHttpResponseHandler callback where you're in need of JsonHttpResponseHandler. Use below code to get the things right on track.

 String AllData=""; AsyncHttpClient client = new AsyncHttpClient();
        client.get("wantedUrl", new JsonHttpResponseHandler(){
            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
                super.onSuccess(statusCode, headers, response);

                //Here response will be received in form of JSONArray
            }

            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                super.onSuccess(statusCode, headers, response);

                //Here response will be received in form of JSONObject
            }

            @Override
            public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
                super.onFailure(statusCode, headers, responseString, throwable);
                Toast.makeText(getApplicationContext(), "We got an error", Toast.LENGTH_SHORT).show();
            }
        });

It works, but how to record the response into a variable of Activity class? (I declared it as a "public static" to access it in onSuccess method, but then outside the above construction it has its previous value (but in onSuccess everything is ok - I tested it with the same Toast) – Justin McGuire Jul 24 '15 at 07:36
@JustinMcGuire you need to learn basic concepts of JAVA for this. No Offence. – Nitin Misra Jul 24 '15 at 07:45
I know that I'm kinda newbie, but anyway I need to record response data into arrays to inflate ListView - so what is the way I can do it? – Justin McGuire Jul 24 '15 at 15:57
@JustinMcGuire you just need not to do that, you've all JSON here in `response` write your iteration code here and put data into arraylist here in `onSuccess()`, you're good to go, try to ready some good articles, you'll easily find plenty of them. – Nitin Misra Jul 24 '15 at 17:00
And I think the last question - how can I get JSONObject from that JSONArray I received from URL using the second onSuccess method from above, not just "getJSONObject – Justin McGuire Jul 25 '15 at 07:48
