I am making an android application using kivy and kivymd. So i followed all the instructions on the documentation page of buildozer and I am facing an error. The modules that I have used are kivy,kivymd,datetime,sqlite3(All of which are written in pure python or contain a recipe).
I have typed all of this inside the buildozer.spec file.
I am running buildozer inside a virtual environment that has python 3.7 on the lastest release of Ubuntu(20)
This is what appear before the error:
[INFO]: -> running python3 -m venv venv
[INFO]: Upgrade pip to latest version
[INFO]: -> running bash -c source venv/bin/activate && pip install -U pip
[INFO]: Install Cython in case one of the modules needs it to build
[INFO]: -> running bash -c venv/bin/pip install Cython
[INFO]: Creating a requirements.txt file for the Python modules
[INFO]: Installing Python modules with pip
[INFO]: IF THIS FAILS, THE MODULES MAY NEED A RECIPE. A reason for this is often modules compiling native code that is unaware of Android cross-compilation and does not work without additional changes / workarounds.
[INFO]: -> running bash -c venv/bin/pip install -v --target '/home/guhan/...(and 146 more)
working: Removed build tracker: '/tmp/pip-req-tracker-e95kbahw'
And this is the errors after that

The same error apears twice in the log
datetime is a built-in python module which comes with python. You need not specify it in the requirements of your buildozer.spec file. Just remove it from requirements and re-run buildozer.
