JSON Parser help

Ok so I have been working on getting this JSON parser to work and I feel the code is right, but I cannot get any results from it. It keeps giving me that the output is Null Node. i am kind of stumped on this as I dont know what I did wrong.

So here is the main activity where the button is pushed it should call the JSONparser and send the internal json file to it.

Code (Java):

1.  
2. import android.os.Bundle;
3. import android.support.v7.app.AppCompatActivity;
4. import android.util.Log;
5. import android.view.View;
6. import android.widget.Button;
7. import android.widget.TextView;
8. import android.view.View.OnClickListener;
9.  
10.  
11.  
12. public class MainActivity extends AppCompatActivity {
13.  
14.     String TAG = "Test ME";
15.  
16.     @Override
17.     protected void onCreate(Bundle savedInstanceState) {
18.         super.onCreate(savedInstanceState);
19.         setContentView(R.layout.activity_main);
20.         final Button bparsejson      = (Button) findViewById(R.id.bparsejson);
21.         final TextView output = (TextView) findViewById(R.id.output);
22.         final String strJson = "{ \"Android\" :[{\"song_name\":\"Gimme Dat\",\"song_id\":\"1932\",\"artist_name\":\"Sidney Samson (Feat. Pitbull & Akon)\"},{\"song_name\":\"F-k The Money (Remix)\",\"song_id\":\"73\",\"artist_name\":\"B.o.B. (Feat. Wiz Khalifa)\"}] }";
23.         final String outputData = null;
24.         Log.d(TAG, "I have started");
25.         /******** Listener for button click ********/
26.         bparsejson.setOnClickListener(new OnClickListener() {
27.             @Override
28.             public void onClick(View v) {
29.                 Log.d(TAG, "Button Pushed");
30.                 JSONParser jp = new JSONParser();
31.                 jp.parsesData(strJson, outputData);
32.                 output.setText(outputData);
33.             }
34.         });
35.  
36.  
37.     }
38.  
39.  
40. }
41.  

And here is the JSON parser code .

Code (Java):

1.  
2. import android.util.Log;
3.  
4. import org.json.JSONArray;
5. import org.json.JSONException;
6. import org.json.JSONObject;
7.  
8.  
9.  
10. /**
11. * Created by MMILLAR on 1/20/2016.
12. * JSON Parser Class
13. * USe this to parse all data which is JSON
14. */
15. public class JSONParser {
16.     JSONObject jsonResponse;
17.     //String OutputData = "";
18.     //String jsonData = null;
19.     String TAG = "JSON Output: ";
20.  
21.     //Consturctor
22.     public JSONParser()
23.     {
24.         //this.jsonData = jsonData;
25.        // this.OutputData = outPutData;
26.     }
27.  
28.     public String parsesData(String jsonData, String outputData)
29.     {
30.         try
31.         {
32.             //Creaate a new JSONObject ith the name/value mapping from the JSON string
33.             jsonResponse = new JSONObject(jsonData);
34.             //Returns the value mapped by the name if it exists and is a JSONArry
35.             JSONArray jsonMainNode = jsonResponse.optJSONArray("Android");
36.  
37.             //Proccess the JSON node
38.             int lenghtJsonArrar = jsonMainNode.length();
39.             for (int i = 0; i<lenghtJsonArrar; i++)
40.             {
41.                 //Get object for each json node
42.                 JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
43.                 //Get the node values
44.                 int song_id = Integer.parseInt(jsonChildNode.optString("song_id").toString());
45.                 String song_name = jsonChildNode.optString("song_name").toString();
46.                 String artist_name = jsonChildNode.optString("srtist_name").toString();
47.  
48.  
49.                 //create the output
50.                 outputData += "Node: \n\n " + song_id + " | "
51.                                             + song_name + " | "
52.                                             + artist_name + " \n\n ";
53.  
54.                 Log.d(TAG, outputData);
55.             }
56.  
57.         } catch (JSONException e) {
58.             e.printStackTrace();
59.         }
60.         return  outputData;
61.     }
62.  
63. }
64.  

Thank you for any help with this I am at a loss of why it is not working.

 

Thanks @LV426 . I am still getting use to andriod debugging. Ill give what you said a go. But, would just one misspelled word force the whole thing to stop working? Or would the parser just skip over it and ignore the error? This is my first Json attempt.
