Activities Mobile Phone

[Dorotea]

Hi There! I'm Italian, sorry for my English not so great.
When I use Spotify on my Android, the others people can't see my activities: they can see them only when I listen spotify music on my computer! I use Spotify more on the mobile phone than on the Computer, and I want that my friends can see what I am listening also by my phone! Can you help me? I had check all the settings...
