Androidカーソルでアプリケーションの強制終了

Question

私は、contactpickerを開くインテントを開始して電話番号にアクセスしようとしています。 私はカーソルを作成しようとするまでうまくいっています。私は連絡先のIDを暴露することができますが、カーソルが初期化された行に、アプリケーションは動作を停止します。

コード：

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (resultCode == RESULT_OK) { 
     Uri result = null ; 
     switch (requestCode) { 
     case 1001: 
      Bundle extras = data.getExtras(); 
      Set<String> keys = extras.keySet(); 
      Iterator<String> iterate = keys.iterator(); 
      while (iterate.hasNext()) { 
       String key = iterate.next(); 
       l(key + "[" + extras.get(key) + "]"); 
      } 
      result = data.getData(); 
      l("Got a result: "+ result.toString()); 

      break; 
     } 
      String id = result.getLastPathSegment(); 
      l("key:" + id) ; 
//Line with the problems , here the app stops 


      Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, new String[]{id}, null); 

      if(cur.getCount() > 0) { 
       while (cur.moveToNext()) { 
        String idst = cur.getString(
           cur.getColumnIndex(ContactsContract.Contacts._ID)); 
       String name = cur.getString(
           cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
       if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 
        //Query phone here. Covered next 
        } 
        } 
      } 
    } else { 

     l("A problem occured"); 
    } 
} 

}
