Directly on Android it seems difficult, unless…
It would be easier to develop directly a specific app which would handle .sif files instead.
And better on a tablet than on a phone, with a Bluetooth mouse, because of usability, ouch…
This is more realistic and would make miracles!
I did some tests on my side with pybind11, starting from studio::App class but no matter what I tried it failed.
The type of the singleton returned by the Instance() is not the same type as the private App() constructor… 
We definitely need scripting features…
