It’s currently not possible to run NoMachine for Android on Chromebook. Chromeos-apk tool doesn’t work with applications that use native libraries. At least if application is compiled to ARM and Chromebook have x86 CPU.
We will investigate if recompilation to x86 can solve that problem.
So currently a only possible way of using NoMachine on Chromebook is a NoMachine Web Player which is a part of NoMachine Cloud Server. You can see how it works by downloading NoMachine Cloud Server evaluation package.
Currently we are working on NoMachine Quick service intended to provide web access without the need for installing NoMachine Cloud Server. Please take a look at the bottom of this page:
