I am an experienced Android developer and with a team of developers we have created a app for Android, a mobile app that is used to mirror the contents of a TV channel. We have had a request to maybe make a PS4 app similar to the one we have on mobile platforms. The question is that is it possible or not? Also would like to know if our physical location is relevant to having a license? We are located in Germany. I am really new to this topic so any advice, hint or whatever if appreciated.
Answer
You need to register as a developer in Sony's Developer portal of your area. For Germany, that would be SIEE (Sony Interactive Entertainment - Europe). You can still ship apps world-wide, but that would be your starting portal. Start at https://www.companyregistration.playstation.com/ and make sure you pick Europe when asked.
Good luck!
