私はこれに苦しんでいます。私はlogcatの出力も添付しています。これで助けてください。私はXAMPP mysqlの中に自分のデータベースを保管しているので、localhost urlからデータベースを呼び出しています。問題は、ListViewが何も表示していないことです。アプリケーションがクラッシュしています。それがないサーバー を指しているため、はモバイル上で使用すべきではないE/AndroidRuntime：致命的な例外：AsyncTask＃2

あなたはここで2つの問題を持っていますモバイル自体。

private static String url_all_products = "http:/127.0.0.1/hul/get_all_products.php";
：httpの後 /を逃す：ので、あなたはURL自体（タイプミス）で間違いを持っ​​ている（XAMPPがインストールされている）は、サーバやテストマシン

2-実際のIPアドレスにそのIPを変更

private static String url_all_products = "http://192.168.1.10/hul/get_all_products.php";
01：

は

private static String url_all_products = "http://127.0.0.1/hul/get_all_products.php";

はそう最終的なURLは（例）のようになりますする必要があります

あるいはドメイン名：

private static String url_all_products = "http://my.api.domain/hul/get_all_products.php";

あなたのサービス応答を外部（ポストマン）で行われた場合、あなたはJavaコードをチェックインする必要があり、マニフェストのインターネットアクセス権を意味します。
