Kivy-Buildozer Android Packaging not working ('buildozer' is not recognized as an internal or external command, operable program or batch file.)

I did not find any solutions for this on the internet.

I am trying to create the Android apk file from my Kivy-Python file on Windows 10.

I followed the standard documentation (e.g. this one or this one).

I installed buildozer using the Pycharm IDE environment.

I open the command box from the path adress bar of the folder with my main python file.

But whenever I type ‘buildozer init’ in the command line, the terminal gives me this error message:

"'buildozer' is not recognized as an internal or external command, operable program or batch file."

What can I do to fix this?

I found no single solution or reference for this. All questions asked are for Ubuntu systems, or for different kind of problems.
