I bought an Android player through Amazon. Here is the description:
COMPLETE AND SIMPLE DIGITAL SIGNAGE SOLUTION: Our XMPS1 Signage Player is a simple digital signage solution that connects to displays and powered by our cloud-based signage server. Our Design Studio lets you design, upload, edit, and manage content remotely anywhere, at any time.
Problem is that it will not boot with SignagePlayer running. I noticed that the Watchdog app is not installed, but I can't find it on the Google Play Store. Any suggestions?
