getting empty response from PHP server - php

Question

Hi friends I am trying to add PHP web services to my ANDROID application, my android code:
userName = userNameField.getText().toString();
passWord = passWordField.getText().toString();
try {
JSONObject json = new JSONObject();
json.put("username", userName);
json.put("password", passWord);
json.put("device_type", "Android");
json.put("lat", "0.0");
json.put("long", "0.0");
JSONObject json1 = new JSONObject();
json1.put("method_name", "checkLogin");
json1.putOpt("body", json);
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpClient client = new DefaultHttpClient(httpParams);
HttpPost request = new HttpPost(URL);
request.setEntity(new StringEntity(json1.toString()));
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response = client.execute(request, responseHandler);
Toast.makeText(this, response, Toast.LENGTH_LONG).show();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Throwable t) {
Toast.makeText(this, "Request failed: " + t.toString(),
Toast.LENGTH_LONG).show();
}
}
Request:
{"method_name":"checkLogin","body": {"username":"someone#some.com","password":"password","device_type":"android","lat":"","long":""}}
expected Response:
[{"status":"1","message":"Login successfully","data":{"id":"xx","username":"someone#some.com","first_name":"xxx","last_name":"yyy","gender":"xxx","relationship":"xxxx","birthdate":"xxxx","hometown":"","major":null,"class":null,"house":null,"device_type":"iphone","current_location_lat":"0.0","current_location_lon":"0.0","profile_image":"no_male_user.png","is_login":"1","created":"2012","status":"1","tag":[{"id":"x","tag_name":"xxxx"},{"id":"x","tag_name":"xxx xxx"}]}}]

Can you check the php code if it gets the required value correctly and executing the the desired method exactly ?
