How to retrieve Contact name and phone number in Android

Question

I'm trying to retrieve contact list with there name and phone numbers. I try following code:

 // Get a cursor over every contact.
    Cursor cursor = getContentResolver().query(People.CONTENT_URI, 
                                               null, null, null, null); 
    // Let the activity manage the cursor lifecycle.
    startManagingCursor(cursor);
    // Use the convenience properties to get the index of the columns
    int nameIdx = cursor.getColumnIndexOrThrow(People.NAME); 

    int phoneIdx = cursor. getColumnIndexOrThrow(People.NUMBER);
    String[] result = new String[cursor.getCount()];
    if (cursor.moveToFirst())
      do { 
        // Extract the name.
        String name = cursor.getString(nameIdx);
        // Extract the phone number.
        String phone = cursor.getString(phoneIdx);
        result[cursor.getPosition()] = name + "-" +" "+  phone;
      } while(cursor.moveToNext());

This code should return an array with the all contacts name and its phone number but this only returns name of the contact and returns NULL in phone number,

Example Output:

 John - null

In Android manifest:

    <uses-permission android:name="android.permission.READ_CONTACTS" />

Then in the activity:

editText.setOnFocusChangeListener(new OnFocusChangeListener(){

            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if(hasFocus){
                    editText.setText("");   
                     Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                     startActivityForResult(intent, PICK_CONTACT);
                }
            }           
        });

And then you have to catch the result of the action pick contact:

@Override 
public void onActivityResult(int reqCode, int resultCode, Intent data){ 
    super.onActivityResult(reqCode, resultCode, data);

    switch(reqCode)
    {
       case (PICK_CONTACT):
         if (resultCode == Activity.RESULT_OK)
         {
             Uri contactData = data.getData();
             Cursor c = managedQuery(contactData, null, null, null, null);
              if (c.moveToFirst())
              {
                  String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));

                  String hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

                  if (hasPhone.equalsIgnoreCase("1")) 
                  {
                      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
                             ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null);
                      phones.moveToFirst();
                      String cNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                       Toast.makeText(getApplicationContext(), cNumber, Toast.LENGTH_SHORT).show();

                      String nameContact = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));

                      editText.setText(nameContact+ " "+ cNumber);
                  }
             }
       }
    }
}
