下载Manger不在Android Pie 9.0中工作(小米mi A2)

作者:互联网

在将设备操作系统更新到Android 9.0时,之前此代码工作正常(小米mi A2).现在,Android Pie 9.0上没有下载文件.

此外,它在Oreo,Nougat,Marshmallow工作正常

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);

logcat中的错误:

这对我有用.经过小米mi A2今天收到软件更新通知.

什么对我有用

在应用程序标记中添加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

This explains the issue in software
