android - 使用 DownloadManager 下载 HTTP/HTTPS URI

Question

我用谷歌搜索并找到了一些相关信息。但这没有帮助。

安卓版本: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，但是还是报错:

02-10 11:18:23.710 E/AndroidRuntime( 7550): java.lang.RuntimeException: Unable to start service com.souyidai.investment.android.service.DownloadService@4344e5e0 with Intent { act=download_with_download_manager cmp=com.souyidai.investment.android/.service.DownloadService (has extras) }: java.lang.IllegalArgumentException: Can only download HTTP/HTTPS URIs:  https://static.test.com/downloads/xxx.apk

这是 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？

我刚刚遇到了同样的问题。出于某种原因，我的网址在“https”之前有一种空白。在 url 字符串上使用 trim() 解决了这个问题。
