下载Manger无法在Android Pie 9.0中运行NetworkSecurityConfig:未使用平台默认值指定网络安全配置 [英] Download Manger not working in Android Pie 9.0 NetworkSecurityConfig: No Network Security Config specified, using platform default

问题描述

在将设备操作系统更新为Android 9.0时，此代码以前工作正常( Xiaomi mi A2 ).现在，文件不在Android Pie 9.0上下载.

On updating the device OS to Android 9.0, previously this code was working fine(Xiaomi mi A2). Now, files are not being downloaded on Android Pie 9.0.

此外，它在Oreo，牛轧糖，棉花糖中都可以正常工作

这是代码段:

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);

logcat错误:

推荐答案

这对我有用.在Xiaomi mi A2今天收到软件更新通知之后.

This worked for me After Xiaomi mi A2 received software update notification today.

对我有用的东西

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，如下图所示

Create xml under res directory and then network_security_config.xml in xml folder like in the picture below

这说明了软件中的问题
