Android无法打开文件

Question

I'm trying to download an apk file from server via DownloadManager:

dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
        DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
        request.setMimeType("application/vnd.android.package-archive");
        request.allowScanningByMediaScanner();
        enqueue = dm.enqueue(request);

When the apk is downloaded and I press it I'm getting "can't open file message",
But if I download that apk via Browser instead of DownloadManger :

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(browserIntent);

The apk works fine.
The device is open for "Unknown sources" and it's version is 4.1.2

What am I doing wrong?

尝试将apk文件保存到本地存储，然后使用直接文件URI打开它
