How is it possible to know what's spotify is playing from an external Android app? -

I just found this settings option in Spotify for the Android Settings screen:

"Device Broadcast Status - Allow other apps on your device to see what you're listening to "

This means that any other app is being played through Spotify . How can this be implemented? Is there a document?

Thanks

The following intentions are in the Spotach: < P> MetadataChained, PlaybackStatched and Quenched.

QEFrited has no additional data.
PlaybackStatired has a Boolean value for "Playing", and there is a value for playback. Artist, album, track, length, and id values ​​are in the Metadatachange com.spotify.mobile.android.metadatachanged

You track (manually or automatically) using com.spotify.mobile.android.metadatachanged P>

If Spotify is paused And has started again, then only PlaybackStatWorld is broadcast
