Q.  Android saying "Can't open file" and not showing Android icon for a downloaded apk

A.  This worked for me.  My server was not setting
the Content-Type in the header correctly.
I was surprised that Android retained this after the download but it did.

For RedHat/Fedora/CentOS add this line to /etc/mime.types

application/vnd.android.package-archive apk
And restart Apache or other webserver
