Question

我用Google搜索并找到了一些相关信息。但这并没有帮助。

Android版：4.0+
这是我的代码：

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

我的网址是https://static.test.com/downloads/xxx.apk

Scheme是https，但我仍然收到错误：

这里是DownloadManager.Request代码：

    public Request(Uri uri) {
        if (uri == null) {
            throw new NullPointerException();
        }
        String scheme = uri.getScheme();
        if (scheme == null || (!scheme.equals("http") && !scheme.equals("https"))) {
            throw new IllegalArgumentException("Can only download HTTP/HTTPS URIs: " + uri);
        }
        mUri = uri;
    }

有什么想法吗？

Answer 1

我遇到了同样的问题。出于某种原因，我的网址在＆＃34; https＆＃34;之前有一种空格。在url字符串上使用trim()解决了问题。

Answer 2

这对我有用：

addAndroidDownloads: {
          mediaScannable: true, // these two lines resolve the crash on first download
          mime: 'image/*', // define mime type also

使用DownloadManager下载HTTP / HTTPS URI
