You must use a Samsung API to upload to the Galaxy Store and that is the error you are getting. You can upload it to Play Store so all Android users can get it not just Samsung users.

If for some reason you must have it in the Galaxy Store then you can sneak it in. See this thread from Stack overflow. but I don’t know if that still works.
