"properties": {    
    "link": "",
    "approvalsReportCount": 3,
    "reportName0": "srcapprovals",
    "reportId0": 164,
    "reportName1": "Approvals",
    "reportId1": 157,
    "requests_report_id": "163",

@KristopherMicinski read OP's question fully. He is having problem of parsing dynamic keys. — Paresh Mayani, Oct 26 '12 at 05:37
Use gson parsing for parsing.It will be more easy for you.Here is the Link http://www.javacodegeeks.com/2011/01/android-json-parsing-gson-tutorial.html — AppMobiGurmeet, Oct 26 '12 at 05:37
@PareshMayani thanks for your credit. And now you can continue with your work. Still, if you think you are good at editing why don't you volunteer, instead criticizing others and their efforts. — Andro Selva, Oct 26 '12 at 05:50

This is the best way i found it to get ReportId value.

Below is My code

JSONObject jObj = new JSONObject(result);
            JSONObject jsonResultArray = jObj.getJSONObject("results");
            JSONObject pro_object = jsonResultArray.getJSONObject("properties");
            Iterator keys = pro_object.keys();
           while(keys.hasNext()) {
                String currentDynamicKey = (String)keys.next();
                String value = pro_object.getString(currentDynamicKey);
                String upToEightCharacters = currentDynamicKey.substring(0, Math.min(currentDynamicKey.length(), 8));

                if(upToEightCharacters.startsWith("reportId"))
                {

                    Log.v("key"," new report ID key  " + currentDynamicKey);
                    Log.v("key"," new report ID key  " + pro_object.getString(currentDynamicKey) );

                }
              }

you can use this

public ArrayList<String> getReportIds() {
    boolean isContinue = true;
    JSONObject json;
    String tag = "reportId";
    int i = 0;
    ArrayList<String> repIdList = new ArrayList<String>();
    JSONObject prop = null;
    try {
        json = new JSONObject("<your json string>");
        prop = json.getJSONObject("properties");
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    while (isContinue) {
        String repId = "";
        try {
            repId = prop.getString(tag + i);
            repIdList.add(repId);
            i++;
        } catch (JSONException e) {
            isContinue = false;
            e.printStackTrace();
        }
    }
    return repIdList;
}

You can Try This!!

try {
               JSONObject jObj = new JSONObject(result);
               JSONObject jsonResultArray = jObj.getJSONObject("results");
               Log.v("log_tag","json result Array :   "+ jsonResultArray);

               JSONObject pro_object = jsonResultArray.getJSONObject("properties");

               Iterator keys = pro_object.keys();

                 while(keys.hasNext()) {
                      // loop to get the dynamic key
                      String currentDynamicKey = (String)keys.next();
                      String value = pro_object.getString(currentDynamicKey);
                      approvaldto_Key = new All_Approval_Key_dto();

                      String upToEightCharacters = currentDynamicKey.substring(0, Math.min(currentDynamicKey.length(), 8));

                      if(upToEightCharacters.startsWith("reportId"))
                      {

                          approvaldto_Key.requestId = pro_object.getString(currentDynamicKey);
                          fetchrecursUserData.add(approvaldto_Key);
                      }

                  }

              }
        catch (JSONException e) {
            e.printStackTrace(); 
            }

          return  fetchrecursUserData;

    }

You can try below code

String serial= jsonObject.getJSONObject("response").getString("serialNumber");

or

JSONObject json;
try {
    json = new JSONObject(buffer.toString());
    String accessToken = json.getString("access_token");
    return accessToken;
} catch (JSONException e) {
    Log.e("Podcast", "There was an error", e);
}
