Step 4:Copy and paste these codes in spreate code cells
!pip install buildozer

!pip install cython==0.29.19
.
!sudo apt-get install -y \
python3-pip \
build-essential \
git \
python3 \
python3-dev \
ffmpeg \
libsdl2-dev \
libsdl2-image-dev \
libsdl2-mixer-dev \

libportmidi-dev \
libswscale-dev \
libavformat-dev \
libavcodec-dev \
zlib1g-dev
.
!sudo apt-get install -y \
libgstreamer1.0 \
gstreamer1.0-plugins-base \
gstreamer1.0-plugins-good
.
!sudo apt-get install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-dev zlib1g-dev libssl-dev openssl libgdbm-dev libgdbm-compat-dev liblzma-dev libreadline-dev libncursesw5-dev libffi-dev uuid-dev libffi6
.
!sudo apt-get install libffi-dev
.
!buildozer init
.
Make sure to rename your python file as main.py
and also upload all the images used in the programe(if used)
navigate to builder.spec file

uncomment and comment these following lines
add __version__ = 0.1
at the top of your main.py
Then
add these Code
!sudo apt install build-essential autoconf libtool
.
pip install --user -U colorama
.
pip install libtool
.
pip install testcase-automaker
.
pip install autoconf
Finally
add this code ...
This will build the apk
!buildozer -v android debug
This Worked for me
Hope this will work for all
