I have json that looks like the following

{  
   "tiles":[  
      {  
         "header":"Manual",
         "subheader":"Login",
         "summary1_label":"",
         "summary2_label":"",
         "summary3_label":"",
         "summary4_label":"",
         "summary1_value":"",
         "summary2_value":"",
         "summary3_value":"",
         "summary4_value":"",
         "iconUrl":"http://ift.tt/1C39tpD"
      },
      {  
         "header":"NewUser",
         "subheader":"Login",
         "summary1_label":"",
         "summary2_label":"",
         "summary3_label":"",
         "summary4_label":"",
         "summary1_value":"",
         "summary2_value":"",
         "summary3_value":"",
         "summary4_value":"",
         "iconUrl":"http://ift.tt/1OVVAUg"
      },
      {  
         "header":"Facebook",
         "subheader":"Login",
         "summary1_label":"",
         "summary2_label":"",
         "summary3_label":"",
         "summary4_label":"",
         "summary1_value":"",
         "summary2_value":"",
         "summary3_value":"",
         "summary4_value":"",
         "iconUrl":"http://ift.tt/1C39tpF"
      }
   ]
}

I cast this as a JsonObject and send it to a reformating method. in that method i do the following

public ArrayList<String[]> formatHttpResponse_SummaryTile(JSONObject json) throws JSONException {
    ArrayList<String[]> arrayList_summary = new ArrayList<String[]>();
    JSONArray tilesArray = json.getJSONArray("tiles");
    //JSONObject allTilesData = json.getJSONObject("tiles");
    for (int i=0; i<tilesArray.length(); i++)
    {
        //JSONObject thisJsonObject = tilesArray.getJSONObject(i);
        JSONArray thisJsonArray = tilesArray.getJSONArray(i);
        String[] thisStringArray = new String[thisJsonArray.length()];
        for (int j=0; j<thisJsonArray.length(); j++)
        {
            thisStringArray[j]=thisJsonArray.getString(j);
        }
        arrayList_summary.add(thisStringArray);
    }
    return arrayList_summary;
}

As you can see i create an array list then cycle through my jsonObjects 3 children. Now the problem is that i want to convert the children to String[][ but my code bugs out at JSONArray thisJsonArray = tilesArray.getJSONArray(i); as it isnt a jsonArray.

Any idea how i can get the children above into 3 string arrays all added to a arrayList Is there a more efficent, straight cast i can do?
