Controlling Android from another Android ?
I have made such project, as the utility to execute remote commands (ping, startapp, installapp...) and remote controlling.
RDP is based on
the screenshots (exchange by my server) and tap emulation..., but ... my RDP is only based on the rooted device, to
emulate taps (commands "input tap ", "input swipe ", "input keyevent "), working rather slow. But i'm OK with the root as the "reboot" of the industrial device (and
app installation without user confirmation) is strongly required also.
No idea how to make it without root (as Teamviewer, AirDroid). But i'm not ready to share the source code, as it is commercial project.
So - yes, it's possible with B4A.
