Java — данные MySQL не отображаются в Android RecyclerView (ошибка Logcat: не удалось загрузить модуль memtrack)

Я только начал разработку приложения для Android. Я использовал XAMPP для создания базы данных (MYSQL) и php для преобразования извлеченных данных в JSON. Однако я не смог отобразить следующий вывод JSON в Android Recyclerview, и при создании этого приложения не было сгенерировано никаких ошибок. Я также сослался на некоторые другие примеры / решения с этого сайта, но я все еще не мог решить эту проблему. Код, который я использовал ниже. Могу ли я узнать, какая часть может быть исправлена ​​или отсутствует?

herblist.php (для преобразования данных MYSQL в JSON)

<?php
include 'dbConnect.php';

// Create connection
$conn = new mysqli($HostName, $HostUser, $HostPass, $DatabaseName);

if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}

mysqli_set_charset($conn, 'utf8');
$sql = "SELECT * FROM herb";

$result = $conn->query($sql);

if ($result->num_rows >0) {
while($row[] = $result->fetch_assoc()) {
$tem = $row;
$json = json_encode($tem);
}

} else {
echo "No Results Found.";
}

echo $json;
$conn->close();
?>

JSON, созданный herblist.php

[{"h_name":"Basil","h_image":"http:\/\/localhost\/Herb\/Herb_image\/basil.jpg"},{"h_name":"Cilantro","h_image":"http:\/\/localhost\/Herb\/Herb_image\/cilantro.jpg"},{"h_name":"Kaffir lime leaf","h_image":"http:\/\/localhost\/Herb\/Herb_image\/kaffir_lime.jpg"},{"h_name":"Lemongrass","h_image":"http:\/\/localhost\/Herb\/Herb_image\/lemongrass.jpg"},{"h_name":"Mint","h_image":"http:\/\/localhost\/Herb\/Herb_image\/mint.jpg"},{"h_name":"Oregano","h_image":"http:\/\/localhost\/Herb\/Herb_image\/oregano.jpg"},{"h_name":"Pandan leaf","h_image":"http:\/\/localhost\/Herb\/Herb_image\/pandan.jpg"},{"h_name":"Parsley","h_image":"http:\/\/localhost\/Herb\/Herb_image\/parsley.jpg"},{"h_name":"Rosemary","h_image":"http:\/\/localhost\/Herb\/Herb_image\/rosemary.jpg"},{"h_name":"Thyme","h_image":"http:\/\/localhost\/Herb\/Herb_image\/thyme.jpg"}]
