Step 1: installing raspbian headless on RASPI 4 Basically flashed and sd card

added a file called ssh (no extension) into the boot [activates ssh]

added a file called wpa_supplicant.conf [connects to wifi]

Boot the pi and wait for the pi to load

On another computer open ssh and connect to [email protected]

Done

Step 2: ADB on raspbian

sudo apt-get install android-tools-adb android-tools-fastboot

test the installation using command using "adb" and "adb start-server"

Step 3: Android Phone

Go to system info, tap on the IMEI serial until it activates developer mode

Go to developer menu and activate adb through usb debugging

Step 2 Part 2:

For python library, I used pure-python-adb

pip install pure-python-adb

Start server using "adb start-server" first, python will not work without this

Step 4: OPENCV

I followed this site: https://www.pyimagesearch.com/2019/09/16/install-opencv-4-on-raspberry-pi-4-and-raspbian-buster/

Other Notes: I have been trying to remote desktop into the PI4 using XRDP. After the initial setup, the PI4 fails to work on both ssh and remote desktop. The best solution I could think of is to avoid remote desktop and the initial installation boot menu altogether. All development will be done remotely via ssh and vscode's ssh capabilities.
