Android : Parser JSON avec async task (méthodes GET et POST)

Veux juste vérifier si ce Parser JSON avec async task est-il bien fait? Quand je mets ce code dans mon Eclipse, cette méthode.equals("POST") a été de souligner en rouge. Et-il dire que cette "méthode" ne peut pas être résolu. Toute suggestion ou aide-t-il? Je vous remercie.

public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
String url=null;
List<NameValuePair> nvp=null;
//constructor
public JSONParser() {
}
//function get json from url
//by making HTTP POST or GET method
public JSONObject makeHttpRequest(String url, String method,
List<NameValuePair> params) {
BackGroundTask Task= new BackGroundTask(url, method,  params);
try {
return Task.execute().get();
} catch (InterruptedException e) {
//TODO Auto-generated catch block
e.printStackTrace();
return null;
} catch (ExecutionException e) {
//TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}
public class BackGroundTask extends AsyncTask<String, String, JSONObject>{
List<NameValuePair> postparams= new ArrayList<NameValuePair>();
String URL=null;
public BackGroundTask(String url, String method, List<NameValuePair> params) {
URL=url;
postparams=params;
}
@Override
protected JSONObject doInBackground(String... params) {
//TODO Auto-generated method stub
//Making HTTP request
try {
//Making HTTP request 
//check for request method
if(method.equals("POST")){
//request method is POST
//defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(postparams));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}else if(method == "GET"){
//request method is GET
DefaultHttpClient httpClient = new DefaultHttpClient();
String paramString = URLEncodedUtils.format(postparams, "utf-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}           
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
//try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
//return JSON String
return jObj;
}
}
}
