En versiones anteriores, la idea era crear una carpeta llamada Media, dentro metíamos otra llamada Audio y ahí creabamos las correspondientes Music, Ringtones, Alarms, Notifications y UI.
Ahora con la nueva estructura de Android, parece que se pueden crear en la SD sin tener que meterlas dentro de Media\Audio. Además hay más carpetas interesantes:
- Music/ - Media scanner classifies all media found here as user music.
- Podcasts/ - Media scanner classifies all media found here as a podcast.
- Ringtones/ - Media scanner classifies all media found here as a ringtone.
- Alarms/ - Media scanner classifies all media found here as an alarm sound.
- Notifications/ - Media scanner classifies all media found here as a notification sound.
- Pictures/ - All photos (excluding those taken with the camera).
- Movies/ - All movies (excluding those taken with the camcorder).
- Download/ - Miscellaneous downloads.
