如何解决：无法从network_security_config解析XML配置

Question

我正在尝试使用 okhttp 从 api 获取 json，当我尝试这样做时，应用程序崩溃了，并且出现运行时异常

Failed to parse XML configuration from network_security_config

我应该怎么做才能解决这个问题？\ni 在我的清单上拥有互联网权限。\ni\'v 试图在其他问题上搜索类似的内容，但找不到答案。

这是我的班级：

class TestActivity : AppCompatActivity() {\n\n  override fun onCreate(savedInstanceState: Bundle?) {\n    super.onCreate(savedInstanceState)\n    setContentView(R.layout.activity_test)\n\n    val adapter = ArrayAdapter<User>(this, android.R.layout.simple_list_item_1)\n\n    listViewTest.adapter = adapter\n    val url = URL(myapi)\n\n    val request = Request.Builder().url(url).build()\n    val client = OkHttpClient()\n    client.newCall(request).enqueue(object: Callback {\n\n        override fun onResponse(call: Call, response: Response) {\n\n            val body = response.body.toString()\n\n            println(body)\n\n\n        }\n\n\n        override fun onFailure(call: Call, e: IOException) {\n\n\n        }\n\n\n\n    } )\n\n\n  }\n}\n

在res中创建一个名为xml的文件夹，并创建一个名为config.xml的文件

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">Your url</domain>
    </domain-config>
</network-security-config>

将其添加到清单文件中的应用程序标记中。

 android:networkSecurityConfig="@xml/config"
