Background media playback
The app plays the “Η Δύναμη της Γνώσης” podcast and the Academy’s guided visualisations with Media3. When the user starts an episode and leaves the app, playback continues in a media playback foreground service. Its controls (play/pause, seek) appear in the notification shade and on the lock screen. The service stops when the user pauses and dismisses the player, or when playback ends.
In the recording: the user taps «Αναπαραγωγή» (Play), goes to the home screen, and the episode keeps playing with media controls in the notification shade.
