While several dSLR cameras do have remote-control APIs that work over USB (here's Canon's), as far as I know they are all proprietary, and don't expose a standard UVC (USB video class) interface.

So while it may be possible to write an Android app that talks to a Canon dSLR, it can't be done via camera2. You'd have to use the Android USB APIs directly, and probably reverse-engineer the Canon SDK, which is only available on Windows and Mac, for the USB protocol.

Android camera2 API supports USB webcams if the V4L drivers match. Even for these, bandwidth is often the bottleneck, because I have not yet seen Android OTG (USB Host-mode) with USB3 performance. USB2 is not capable of passing full HD video at 30FPS.

Worse with DSLR camera. Even if it has V4L-compliant USB interface, it is probably tuned for the highest edge, not the mediocre USB2 capabilities of Android hosts.
