This was really about time! A feature, so far only available for iOS, is now also available for Android. With its recent update of the Sonos Controller for Android, Sonos introduced today, the possibility to push on an Android devices stored media files and playlists to a Sonos system, similar to DLNA but not following the DLNA standard. This means users, which have files and playlists locally stored, can finally play them on their Sonos systems. This includes, for instance, Podcasts, other downloaded or synchronized media files and playlists. So far, the Sonos system had to be either connected to media files, stored on a PC or NAS in the same LAN, or streaming services like Spotify, Radio, Deezer or others.
On the device stored files or playlists can only played through the updated Sonos Controller for Android. It's neither possible to use another media player and therefore it's also not possible to stream yet not supported services like Google Music from an Android device to the Sonos system
