Hi! I am updating contact using below code. I am unable to get contact detail by phone number. cursor count is always returning 0, please check it.I think m missing some thing. Need urgent help

cursor = getContentResolver().query(Contacts.Phones.CONTENT_URI, null, Contacts.Phones.NUMBER+" = ?", new String[]{phoneNumber}, null);
        Log.d("UpdateContact", phoneNumber);
        Log.d("UpdateContact", String.valueOf(this.cur.getCount()));
        if(this.cur.moveToFirst())
        {           
            String id = cur.getString(cur.getColumnIndex(People._ID));  
            Uri baseUri = Uri.withAppendedPath(People.CONTENT_URI, id);

            ContentValues values = new ContentValues();             

            values.put(Contacts.Phones.NAME, "OO "+name); 


            this.cr.update(baseUri, values, null, null);



            //update email
            Cursor cursor = 
                this.cr.query(Contacts.ContactMethods.CONTENT_URI,
                                        new String[] { Contacts.ContactMethods._ID },
                                        Contacts.ContactMethods.PERSON_ID + " = " + id,
                                        null, null);

            Uri emailUri = Uri.withAppendedPath(baseUri, People.ContactMethods.CONTENT_DIRECTORY);

            values.clear();

            values.put(People.ContactMethods.KIND, Contacts.KIND_EMAIL);
            values.put(Contacts.ContactMethods.TYPE, People.ContactMethods.TYPE_OTHER);
            values.put(People.ContactMethods.DATA, email);

            if(cursor.moveToFirst())
            {   
            String personId = cursor.getString(0);

            this.cr.update(Uri.withAppendedPath(emailUri, personId), values, null, null);
            }
            else
            {               
                this.cr.insert(emailUri, values);
            }
            return true;
