问题描述
我在Google上搜索了一下.但这无济于事.
I googled and find something about this. But that doesn't help.
Android版本:4.0+
这是我的代码:
Android Version: 4.0+
here's my code:
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
我的网址是 https://static.test.com/downloads/xxx.apk
方案是https,但仍然出现错误:
Scheme is https, but I still get an error:

这是DownloadManager.请求代码:
Here's the DownloadManager.Request code:
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?
推荐答案
我只是遇到了同样的问题.由于某种原因,我的网址在"https"之前有一种空白.在URL字符串上使用trim()
解决了该问题.
I just had the same problem. For some reason, my url had one kind of white space before the "https". Using trim()
on the url String solved the problem.
