ModuleNotFoundError: No module named 'google.protobuf' on apk

Software Versions

Python: 3.8.5 (default, Sep 5 2020, 10:50:12)
OS: Manjaro Linux
Kivy: v1.11.1
Kivy installation method: through pip

Describe the bug I've created an app which uses pyrebase module for firebase. I've created the apk with buildozer. But when I want to post something (post data to firebase, works on PC), app just closes automatically.

I've run adb logcat and found, ModuleNotFoundError: No module named 'google.protobuf'

adb logcat

#    You can define all the "list" as [section:key].

#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#

#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
