Do you already have code you can share with us?

It's in the gitlab repository here https://git.project-insanity.org/onny/nextcloud-app-radio

sorry @MariusBluem my fault, now its completley public

@onny Just seen that your license value of your Info.xml is MIT license. I think only AGPL, MPL or Apache is supported by the appstore as value ...

See: https://nextcloudappstore.readthedocs.io/en/latest/developer.html

There was a change recently which adds MIT, not sure if it's deployed already though

👍

So should I change the license or could I stick with MIT?

Certificate at https://github.com/nextcloud/app-certificate-requests/blob/6090a6dae470847fb747b547b3a3aa0663664b2e/radio/radio.crt :)

About the license, I'd suggest just try if the current deployed appstore version supports MIT, if not change the license or wait until the app store has been updated.
