java.lang.Nullpointerexception en utilisant JSONParser

J'utilise la base de données MySQL, et je choisis mes données de la base de données en utilisant JSONParser.class que j'ai trouvé sur Internet, mais la valeur toujours montrant Null, s'il vous plaît aider, je suis nouveau à cejava.lang.Nullpointerexception en utilisant JSONParser

Voilà ma principale classe d'activité:

public class Profil extends Activity{ 
    private static String url = "http://10.0.2.2/koperasidb/tampil_profil.php"; 
    private static final String TAG_ANGGOTA = "anggota"; 
    private JSONParser jsonParser; 
    private JSONObject json; 
    private JSONArray jArray; 

    String kodeanggota; 
    private Session session;//global variable 
    private String no_ba,nm,jk,agama,tmptlahir,tgllahir,blnlahir,thnlahir,status,alamat,notelp,email; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     session = new Session(this); //onCreate Session class 
     //mengambil string kdanggota 
     kodeanggota = session.getkdanggota(); 

     jsonParser = new JSONParser(); 
     ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>(); 
     postParameters.add(new BasicNameValuePair("kode", kodeanggota)); 
     //profil = new ArrayList<HashMap<String, String>>(); 
     try { 
      json = jsonParser.makeHttpRequest(url, "POST", postParameters); 
      jArray = json.getJSONArray(TAG_ANGGOTA); 
      for (int i = 0; i < jArray.length(); i++) { 
       JSONObject job = jArray.getJSONObject(i); 
       no_ba = job.getString("no_ba"); 
       nm = job.getString("nama"); 
       jk = job.getString("jk"); 
       agama = job.getString("agama"); 
       tmptlahir = job.getString("tmptlhr"); 
       tgllahir = job.getString("tgllhr"); 
       blnlahir = job.getString("blnlhr"); 
       thnlahir = job.getString("thnlhr"); 
       status = job.getString("status"); 
       alamat = job.getString("alamat"); 
       notelp = job.getString("notelp"); 
       email = job.getString("email"); 

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

    private void tampilkanprofil() { 
     TextView profilnama = (TextView) findViewById(R.id.profilnamaanggota); 
     profilnama.setText(nm); 
     TextView profiljk = (TextView) findViewById(R.id.profiljk); 
     profiljk.setText(jk); 
     TextView profilnoba = (TextView) findViewById(R.id.profilkodeba); 
     profilnoba.setText(no_ba); 
     TextView profilagama = (TextView) findViewById(R.id.profilagama); 
     profilagama.setText(agama); 
     TextView profilttl = (TextView) findViewById(R.id.profilttl); 
     profilttl.setText(tmptlahir + ", " + tgllahir + " " + blnlahir + " " + thnlahir); 
     TextView profilstatus = (TextView) findViewById(R.id.profilstatus); 
     profilstatus.setText(status); 
     TextView profilalamat = (TextView) findViewById(R.id.profilalamat); 
     profilalamat.setText(alamat); 
     TextView profilnotelp = (TextView) findViewById(R.id.profilnotelp); 
     profilnotelp.setText(notelp); 
     TextView profilemail = (TextView) findViewById(R.id.profilemail); 
     profilemail.setText(email); 
    } 
}

Et voici mon fichier php:

<?php 
include ("koneksi.php"); 

$response = array(); 
$kd=$_POST['kdanggota']; 
$result = mysql_query("SELECT * FROM anggota_baru WHERE kd_anggota ='$kd' ") or die(mysql_error()); 

$response["anggota"] = array(); 
while($row = mysql_fetch_array($result)){ 
    $profil = array(); 
    $profil["no_ba"] = $row["no_ba"]; 
    $profil["nama"] = $row["nama_lengkap"]; 
    $profil["jk"] = $row["kelamin"]; 
    $profil["agama"] = $row["agama"]; 
    $profil["tmptlhr"] = $row["tempat_lahir"]; 
    $profil["ttgllhr"] = $row["tgl_lahir"]; 
    $profil["blnlhr"] = $row["bln_lahir"]; 
    $profil["thnlhr"] = $row["thn_lahir"]; 
    $profil["status"] = $row["status_nikah"]; 
    $profil["alamat"] = $row["alamat"]; 
    $profil["notelp"] = $row["no_telp"]; 
    $profil["email"] = $row["email"]; 

    array_push($response["anggota"],$profil); 
} 
echo json_encode($response); 
?>

voici mon erreur logcat:

Et votre logcat? Où est le NPE? – 323go

'jArray' peut être' null'. S'il vous plaît vérifier – Keerthivasan

Vous paramètre de passage de l'application client avec le nom « Kode » en ligne

postParameters.add(new BasicNameValuePair("kode", kodeanggota));

Mais vous acceptez avec le nom « kdanggota » en ligne

$kd=$_POST['kdanggota'];

Par conséquent serveur envoie vide tableau et vous ne vérifiez pas que le tableau est vide ou non. Veuillez utiliser le même nom de paramètre lors de l'envoi et de la réception de données.

oui thx je dois avoir oublié – user3488298

une erreur que je peux voir sans le logcat qui est comme suit;

1 - Vous avez attribué kode clé dans votre BasicNameValuePair pendant que vous essayez de chercher 'kdanggota' en vous php Wile dans $_POST qui n'existe pas. Donc, changer la quatrième ligne de php comme suit

`$kd=$_POST['kode'];` //You need to write kode here because that is what is the key for your pair.

S'il vous plaît poster aussi logcat pour plus d'informations
