我已经定义了一个自定义的网络安全配置,在我的清单包括它作为推荐这里

RES/XML/network_security_config.xml:

  <?xml version="1.0" encoding="utf-8"?>
  <network-security-config>
  <domain-config cleartextTrafficPermitted="true">
    <domain includeSubdomains="true">127.0.0.1</domain>
    <domain includeSubdomains="true">localhost</domain>
  </domain-config>
  </network-security-config>

这是我的Android.manifest:

    <application android:icon="@drawable/icon" 
             android:allowBackup="false"
             android:usesCleartextTraffic="true"
             android:networkSecurityConfig="@xml/network_security_config"
             android:label="@string/app_name"
             android:theme="@style/AppTheme"
             android:persistent="true" >

尝试通过HTTP与127.0.0.1进行通信时,即使有这些更改,我也会在logcat中看到这一点:

08-09 10:50:34.395 30791  3607 D NetworkSecurityConfig: Using Network Security Config from resource network_security_config debugBuild: true
08-09 10:50:34.397 30791  3607 D NetworkSecurityConfig: Using Network Security Config from resource network_security_config debugBuild: true

我正在尝试开发显示视频的应用程序，您可以下载它我正在使用下载管理器类，但它没有用，也没有给我任何错误:(

这是我的下载管理器代码：

    public void downloadFileFromUrl(String url, String fileName) {

        String filePath=Environment.getExternalStorageDirectory() + File.separator + "BlueNet";

        File folder = new File(filePath);

        if (!folder.exists()) {
            folder.mkdirs();
        }

        try {

        Uri downloadUri = Uri.parse(url);
        DownloadManager.Request request = new DownloadManager.Request(downloadUri);

        request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI);
        request.allowScanningByMediaScanner();

        request.setDestinationInExternalPublicDir("/BlueNet/",fileName);
        request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
        request.setVisibleInDownloadsUi(true);
        DownloadManager downloadManager = (DownloadManager)getApplicationContext().getSystemService(DOWNLOAD_SERVICE);
        long id= downloadManager.enqueue(request);
            Toast.makeText(this, fileName, Toast.LENGTH_LONG).show();
            Toast.makeText(this, filePath, Toast.LENGTH_LONG).show();

        }

        catch (Exception ex){
            Toast.makeText(this, ex.toString(), Toast.LENGTH_LONG).show();
        }
    }

这就是我的称呼

downloadFileFromUrl(path, fileName);

在哪里：

路径：“192.168.1.5:8080/BlueNet_NMC/blue_elephant.mp4”

文件名：“blue_elephant.mp4”

我已经将此权限授予清单
