Hello,
I would try some tests with system/child_process on android.
But what is accessible ?
Can I use Linux Shell on the phone like I can do with ADB ?
How could I call an app and communicate with it ?
I didn’t find any example :-/
Thank you 
I haven’t tried it out. I would just go ahead and try copy pasting
examples. Do you know how to use WebIDE to connect to simular/device, it
makes it real easy.
I understand why you would ask first before trying if you didn’t know how
to copy paste examples. Only other way to test is to build a package and
then get it onto the device somehow (email or other complicated means).
