Ah, that manpage ist very helpfull.
I want to execute a script in the scope of the container.
And I'm not shure, if its needed to populate any working-paths to the container, but when it is needed, I want to know how.
qDslrDashboard is not meant to control the internal phone camera.
It is for controlling an external DSLR connected over wifi or usb.
So integration into camera-app doesn't make sense.
For now, I just want to figure out, what would be needed, to get it running on the phone.
Then perhaps I could contact the developer to ask for a possibilities to create an uvports app...
