DroidBOX Share is a multi-screen interaction application for smart phone or tablet to interact with DroidBOX T8-S. This app is for your Android phone or tablet, if you have a DroidBOX T8-S
With DroidBOX Share you can:
stream any audio or video file to your T8-S
open apps remotely
use your Smartphone as Remote Control for your T8-S
Installing this application on a different DroidBOX model (or indeed the T8-S) won't give you DroidBOX Share functionality. This app is the client, the server app is ONLY found on the DroidBOX T8-S.
