Android: unable to retrieve data from json -


I am getting an id of some event for this activity from previous activity and passing this ID in the current activity URL The name of the city that is being found in the URL is my code. 

  string s = getIntent (). GetStringExtra ("AR"); Try {HttpPost hpost = New HTTP Post ("xxxxxxxxxxxxxxxxx / id"); HttpResponse response = login.client.execute (hpost); & Lt; NameValuePair & gt; NameValuePairs = New ArrayList & lt; NameValuePair & gt; (1); NameValuePairs.add (New BasicNameValuePair ("id", s)); Hpost.setEntity (new UrlEncodedFormEntity (nameValuePairs)); String re = entityUtils.toString (response.getEntity ()); System.out.print (ri); JSONObject Root = New JSONObject (Re); EveState.setText (root.getString ("cityname")); } Hold (exception e) {Log.e ("exvcx", "Error obtaining data" + e.toString ()); }   
 The exception that I'm getting is no value for the  city name . I think I am unable to pass the ID to this URL..Please tell this the right way? If so, then provide the solution to the problem otherwise please correct me where I am doing wrong. Thank you. " "Position": "try" entry "", "response": 1, "response": "try to enter", "phnumber": ["id": "73", "name": "dangerous", "address": "rigdog", "location" : "2467568", "created": "2012-07-11 06:24:31", "picture": "4ffd626f021487.45227344.jpg", "block": "n" "destroyed": "n" "Cityname": "juno", "statename": "alaska", "interestname": "comic", "user name": "princeb", "EVENTDATE": "2012- 07-13 15:45:29, "Format": "July 13, 2012"}], "ImageWith": 1024, "ImageHit": 1024}

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no.
