Welcome,

Can you show where you found the project and also show your relevant blocks.

jukebox

I assume you're talking about @Taifun's jukebox aia. This is from 2016, uses an ancient version of the TaifunFile extension and does not request READ permission. Update the extension and request READ permission at the beginning (at least on devices with Android < 11).

As it lists audio files from the Shared folder /Music it should work on Android 11+ without READ permission.

@Anke

As it lists audio files from the Shared folder /Music it should work on Android 11+ without READ permission.

More precisely: Of course only if the audio files are created by the app itself. Otherwise you must request READ permission on Android 11+ as well (i.e. on all Android versions).
