Ive tried two commands:

Quote:

buildozer -v android debug

and

Code:

buildozer android debug deploy run

I have installed python3.8 and 3.7, and I am aware that Kivy hasn't released a wheel for 3.8 yet. Anyways I have done everything I could to use just python 3.7 to build this app, but I still get the error. I can't work out what is going wrong and I can't find any alternative for Buildozer

I was told to use OpenJDK8 and It worked a little bit further, but then I got this error back:

My computer is in spanish so I'll translate the spanish bits:

No se puede crear el enlace simbólico a «A»: Función no implementada > Can't create symbolic link «A»: Function not implemented

Se sale con estado de fallo debido a errores anteriores > It comes with failure status due to previous errors
