Android 找不到文件异常："；URL"；用于解析XML数据

我正在尝试从localhost URL解析XML数据。我使用DOM解析方法。我一直在获取URL上未找到文件的异常错误。我已经在浏览器上测试了URL，它运行良好。请看一下我的代码

    private fun loadData(){
            try {
                val url = URL("https://wdifid.themall.co.th/sap/opu/odata/sap/ZMATERIAL_DETAIL_SRV/PlantSet?&sap-client=130")
                val conn: URLConnection = url.openConnection()
                try {
                    val dbFactory: DocumentBuilderFactory = DocumentBuilderFactory.newInstance()
                    val dBuilder: DocumentBuilder = dbFactory.newDocumentBuilder()
                    val s = InputSource(conn.getInputStream())
                    val doc: Document = dBuilder.parse(s)
                    doc.documentElement.normalize()
                    
                }
                catch(e:Exception) {
                    e.printStackTrace()
                }

            } catch (e: Exception) {
                e.printStackTrace()
            }
        }

这就是错误所在
