Firebase-admin causing 'ModuleNotFoundError: No module named'google.auth'' in Kivy/KivyMD-built Android app: how to solve it?

I am trying to build an adnroid app using Kivy and KivyMD. After building it. Android app is getting stopped. I saw the log using adb logcat. it says "ModuleNotFoundError: No module named 'google.auth'". I have added all dependency in builder.spec. I have allowed internet permission in build.spec.

Here is the solution that worked just fine:
I have found out that google modules are, or i can say module like
google.cloud, google.storage and etc

Are stored in a file named google you can navigate it in your environment
"env/../../site-packages/google"
So what i did i went in this path in my .buildozer folder
.buildozer/android/platform/build-armeabi-v7a/build/python-installs/yummycom/google
yummycom is my project name ignore it

So i compared it with my google folder in my env and i just copy whats in it
and i pasted there and it worked just fine for me
because when its goes in that directory they are missing though you include them in your requirement
100% WORKED
