DLAN based wireless speaker (raspberry pi)

some passages:

Android doesn’t have built-in support for any media streaming technology (AirPlay, DLNA, Miracast). Samsung Link (formerly AllShare) is also based on DLNA

Spotify Connect: which will allow to stream directly from Spotify app on your Android to any Spotify Connect-enabled receiver. Unfortunately as of today, the feature is available only in a short list of HiFi brands.

Chromcast:

Chromecast is another name that has been lately gaining popularity. Even Google Music supports Chromecast streaming. However, Chromecast dongle uses HDMI interface, very popular for video, which you will not easily find in HiFi devices.
