下载管理器在 Android Pie 9.0 NetworkSecurityConfig 中不工作：未指定网络安全配置，使用平台默认值
Download Manger not working in Android Pie 9.0 NetworkSecurityConfig: No Network Security Config specified, using platform default
将设备 OS 更新为 Android 9.0，之前此代码运行良好（小米 mi A2）。现在，文件未在 Android Pie 9.0.
下载
此外，它在奥利奥、牛轧糖、棉花糖中效果很好
这是代码片段：
File myDir = new File(Environment.getExternalStorageDirectory(), "MyApp");
if (!myDir.exists()) {
myDir.mkdirs();
}
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
Locale.getDefault()).format(new Date());
DownloadManager mgr = (DownloadManager) context.getSystemService(Context.DOWNLOAD_SERVICE);
Uri downloadUri = Uri.parse(url);
DownloadManager.Request request = new DownloadManager.Request(
downloadUri);
request.setAllowedNetworkTypes(
DownloadManager.Request.NETWORK_WIFI
| DownloadManager.Request.NETWORK_MOBILE).setAllowedOverMetered(true)
.setAllowedOverRoaming(true).setTitle("Downloading demo file").
setVisibleInDownloadsUi(true)
.setDestinationInExternalPublicDir(folder_main + "/", timeStamp);
mgr.enqueue(request);

今天 Xiaomi mi A2 收到软件更新通知后，这对我有用。
什么对我有用
在 application 标签中添加 android:networkSecurityConfig="@xml/network_security_config"
<application
android:name=".ApplicationClass"
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:networkSecurityConfig="@xml/network_security_config"
android:supportsRtl="true"
android:theme="@style/AppTheme">
其中 network_security_config.xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<base-config cleartextTrafficPermitted="true" />
</network-security-config>
在res目录下创建xml，然后在xml文件夹中创建network_security_config.xml，如下图
