I only tested the Linux Version, so here a short manual:
– download android app and install
– download pc programm from site (chmod a+x networktablet-x86_64)
– run in a terminal the download pc programm (./networktablet-x86_64)
– run app on smartphone
If you have Dual Monitors:
in my case it was “Network Tablet”
note the device name and resolution settings of the device the tablet should be used for
xsetwacom set "Network Tablet" MapToOutput "1680+1050+1680+0"
if the xsetwacom cant use the display Name, use the resolution settings instead.
(in my case i had to use the resolution settings instead of display name)
