This question already has an answer here:
I've looked a lot for the way that to connect Android smart phone to Raspberrypi via USB. Most of articles explain how to stream camera over network ... that means to control Raspberry Pi camera using Android
what I need is the opposite:
I want to use my Android phone as a camera (connected via USB) to be able to capture images using its camera.
I need all that to avoid the redundancy of webcam and to have better resolution
I'm grateful for any help or suggest.
