android - 使用 DownloadManager 以编程方式下载 Apk 文件后无法打开

Question

我已经使用 DownloadManager 从 http 本地服务器成功下载了 jpg 图像。同样，我尝试从 http 本地服务器下载 apk。Apk 正在成功下载。但是当我单击 Apk 时，它显示错误“解析包时出现问题”。以下是该问题的 logcat 跟踪。

代码

private long downloadImage(Uri downloadUri, Uri destinationUri){
        long downloadReference;

        downloadManager = (DownloadManager) this.context.getSystemService(Context.DOWNLOAD_SERVICE);

        DownloadManager.Request request = new DownloadManager.Request(downloadUri);
        
        request.setMimeType(MIME_TYPE);//MIME_TYPE = "application/vnd.android.package-archive";
        request.setTitle(FILE_NAME);//my_file.apk
        request.setAllowedOverMetered(true);
        request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI);
        request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE);
        request.setDescription("Apk is downloading...");
        
        request.setDestinationInExternalPublicDir(this.context.getExternalFilesDir(
                    Environment.DIRECTORY_DOWNLOADS) + "/NewFile", FILE_NAME);//FILE_NAME = my_file.apk
        request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
        downloadReference = downloadManager.enqueue(request);


        return  downloadReference;
    }

你能帮我解决这个问题吗？
