I can do this with samsung galaxy tab s and garmin edge 800. You need 2 more things. a micro usb (otg)adapter for the tablet and the Sportable app. You plug your edge 800 into the micro adapter and the Sportable app should be able to recognize your device. Then, you can export the activity to your garmin account. You can also get the garmin connect mobile app and use that to view your results.

This is how I can transfer my activity with my tablet.
