Json Android

Ciao sto tentando di fare una app che mi legge i dati in locale da un db access , ho realizzato un script Php che mi da un autput che funziona;

<?php

/* La query SQL,  */
$query="select *from tabripa" ;

/* I parametri di connessione */
$path= "D:/OneDrive/Programmazione/Android/" ;
$db_name= "dati.mdb" ;
$dsource=$path.$db_name ;
$cn_string="Provider=Microsoft.Jet.OLEDB.4.0;" ;
$cn_string.="Data Source=$dsource;" ;
$cn_string.="Jet OLEDB:Database Password=gmpa";


$response = array();

/* La connessione */
if (!file_exists($dsource) ){

die("Il database non esiste") ;

}
$cn= new COM("ADODB.Connection");
$cn->open($cn_string) ;

/* Istanziamo un oggetto Recordset
e inviamo la query attraverso
il metodo Open() */
$rs= new COM("ADODB.Recordset") ;
$rs->Open($query,$cn) ;

/* Ciclo per recuperare i valori dal recordset
EOF= tutto il set di dati è stato esaminato 
e il cursore è giunto in fondo */
if (!$rs->EOF) {
    // looping through all results
    // products node
    $response["tabripa"] = array();
    
    while (!$rs->EOF) {
        // temp user array
        $product = array();
        $product["pid"] = $rs -> Fields["Nbusta"]->value;
        $product["name"] = $rs -> Fields["costo"]->value;
       // $product["price"] = $rs -> Fields["costo"]->value;
       // $product["description"] = $rs -> Fields["descrizione"];
       // $product["created_at"] = $row["created_at"];
       // $product["updated_at"] = $row["updated_at"];

	    $rs -> MoveNext();


        // push single product into final response array
        array_push($response["tabripa"], $product);
    }
    // success
    $response["success"] = 1;

    // echoing JSON response
    echo json_encode($response);
} else {
    // no products found
    $response["success"] = 0;
    $response["message"] = "No products found";

    // echo no users JSON
    echo json_encode($response);
}

/* Chiusura Recordset (da non farsi nelle query di comando) */
$rs->Close() ;

/* Pulizia dell’oggetto Recordset */
//$rs->Release() ;
//$rs= null ;



?>

Questo è la parte finale del Log cat

non vedo errori,fa per caricare i dati però la lista è vuota.
