I have successfully built a custom viewer app and loaded it on my ipad but I cannot figure out how to view a folio in it.
I tried publishing my folio, sharing it even creating a new folio with the sideload option for local build. Nothing I can see creates a .folio file. The portal only allows me to export a .zip file.
An guidance on how I can actually test my custom app with a real folio short of actually publishing it?
If I open my custom viewer app while connected to my mac via USB I don't have the view on ipad option like I do with the Adobe Content Viewer.
Your custom app shows only folios published as public. In the Folio Producer Organizer, select the folio and choose Publish. Choose Public and Free (I assume it's not retail), and specify a Product ID. If you used the same Adobe ID to publish the folio that you specify in the Title ID field of your custom app, the folio should show up.
