How to display package / app icon when browsing Cydia repo

Question

I have successfully created a Cydia repo, and am hosting an app that I am developing, and it installs fine, but for some reason I can't get the app icon to display when clicking the package in Cydia. As of right now the app icon in Cydia looks like the following,

The app icon shows when the app is installed on the device, and I was told the app needs to be installed before the icon will show up in Cydia, so I installed the app on my device, but the icon is still not showing up. I also added the Icon: file:/// line to the control file. I can't seem to figure out why the icon isn't showing, as of right now, the control file looks like,

Answer 1

Yes, the Packages file makes a difference.

To include Icon field in Packages file You need edit dpkg-scanpackages script and add "Icon" to the end of the array fieldpri.

Here is my fieldpri used for Cydia repo.

my @fieldpri = ('Package','Source','Version','Priority','Section','Essential','Maintainer','Pre-Depends','Depends','Recommends','Suggests','Conflicts','Provides','Replaces','Enhances','Architecture','Filename','Size','Installed-Size','MD5sum','Description','Origin','Bugs','Name','Author','Homepage','Website','Depiction','Icon');
