YAACC is an Android UPnP controller. It allows you to discover, use, and control UPnP devices on your network to stream media files. Since it's a subset of UPnP, it is also capable of communicating with DLNA devices. It is possible to start a UPnP server on your device in order to play media from your device on any UPnP renderer in your network. If you start the YAACC UPnP renderer service, you are able to control your device by another UPnP controller in the network. This is quite useful for Android HDMI sticks plugged into your TV. If you install YAACC on them and start the UPnP renderer service, you are able to stream media file to it using YAACC on your smartphone or tablet.
