代码适用于模拟器，但不适用于物理设备

Question

我有代码，我正在尝试提交到数据库，并且代码在模拟器上正常工作但是一旦我移动到实际设备，相同的代码将不再起作用。我认为它与我的php中的time（）函数有关（我不知道它可能是什么）但是我错过了一些明显的东西吗？在物理Android设备上的这个代码总是抛出“哎呀！发生错误。”但是在我的电脑上我的模拟器上工作得很好。我已经检查过以确保我上传了该项目的新副本。

<?php

/*
 * Following code will create a new product row
 * All product details are read from HTTP Post Request
 */

// array for JSON response
$response = array();

// check for required fields
if (isset($_POST['assemblyLotNumber']) && isset($_POST['assemblyID']) && isset($_POST['assemblerID']) && isset($_POST['quantity'])) {

    $assemblyLotNumber = $_POST['assemblyLotNumber'];
    $assemblyID = $_POST['assemblyID'];
    $assemblerID = $_POST['assemblerID'];   
    $quantity = $_POST['quantity'];

    // include db connect class
    require_once __DIR__ . '/db_connect.php';

    $time = time();
    // connecting to db
    $db = new DB_CONNECT();

    // mysql inserting a new row
    $result = mysql_query("INSERT INTO assemblylot (assemblyLotNumber, assemblyID, assemblerID, date, isPremade, quantity) VALUES('$assemblyLotNumber', '$assemblyID', '$assemblerID', $time, 1, '$quantity')");

    // check if row inserted or not
    if ($result) {
        // successfully inserted into database
        $response["success"] = 1;
        $response["message"] = "premade assembly successfully created.";
        $response["date"] = $time;
        // echoing JSON response
        echo json_encode($response);
    } else {
        // failed to insert row
        $response["success"] = 0;
        $response["message"] = "Oops! An error occurred.";
        $response["date"] = $time;
        // echoing JSON response
        echo json_encode($response);
    }
} else {
    // required field is missing
    $response["success"] = 0;
    $response["message"] = "Required field(s) is missing";

    // echoing JSON response
    echo json_encode($response);
}
?>

这是我在代码中调用的地方

public void submitAssemblyLot(Assembly a) {
        List<NameValuePair> assemblyParam = new ArrayList<NameValuePair>();
        assemblyParam.add(new BasicNameValuePair("assemblyLotNumber", Integer.toString(a.getAssemblyLotNumber())));
        assemblyParam.add(new BasicNameValuePair("assemblyID", Integer.toString(a.getAssemblyID())));
        assemblyParam.add(new BasicNameValuePair("assemblerID", Integer.toString(a.getAssemblerID())));     
        try {
            JSONObject json = jsonParser.makeHttpRequest(
                    url_submit_assembly_lot, "POST", assemblyParam);
            String message = json.getString("message");
            String date1 = json.getString("time");
            Log.d("submitAssemblyLot", message);
            Log.d("submitAssemblyLot", date1);
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
