kivy-ios | Toolchain compiling Python / Kivy / other libraries | iOS library

I created an APK from Python Kivy & KivyMD, using Google colab. after installing it in my phone (android) , it crashed. there two file in my project main.py, main.json, I have correctly listed Kivy & KivyMD in the requirements in the Buildozer.spec file. (kivy==2.0.0,kivymd==0.104.2) and I add json to included source like this:
source.include_exts = py,png,jpg,kv,atlas,json

This is my code..

main.py: it is a simple Notes app I think that there is no error

I'm making a kivy app for samsung and compiling it using buildozer, ubuntu on windows.

This is .spec file:

I am trying to create a kivy app for android device. And my code is working great on the PC. But the apk file created using buildozer is not really working on the android. It crashes before opening. But a simple Hello World Example works perfect With the same spec file.. I am not at all using any external modules in the app. Only socket module (which is a python core module.)

I don't know, what is happening. So I used socket to create a functionality to try the code and in exception I have given the code to send the Exception to my IP. Also I am having a program ready to receive and print the signal. Both these things worked great on the PC. But apk still crashes. Without sending any logs to my PC.

Here is the spec file:

I have created an APK file from Python Kivy & KivyMD, using Buildozer. When I open the app after installing it, it shows the splash image and then closes. I have checked and found that their seems no issue in the main.py, as I have correctly listed Kivy & KivyMD in the requirements in the Buildozer.spec file. (kivy==2.0.0,kivymd==0.104.1)

This is my code..

main.py

from kivy.uix.screenmanager import Screen from plyer import call from plyer.platforms.android import activity from kivy.utils import platform import os

I encountered an error while trying to compile my kivy app using buildozer. It's telling me no such file or directory. When I went to check the directory it's Reminder__armeabi-v7a/project.properties but it seems it needs the directory as Reminder system__armeabi-v7a/project.properties. I don't know if it's advisable to rename the directory because I didn't create the directory. It was created automatically during the build process. Also when I tried renaming the folder to "Reminder system__armeabi-v7a/project.properties", I got the error saying "toolchain.py: error unrecognized argument system system", so I reverted the changes made, and I'm looking for another solution.

My buildozer.spec file looks like this:

I'm trying to make kivy app for android that has some simple network features. The app works fine on pc but when I try to import it to android it doesn't work anymore. At first my app crashed on startup which was apparently caused by having network stuff on my main thread so I moved all the network stuff to another thread so my app doesn't crash anymore but it doesn't work either. Here is where I make new thread for networking:

I'm a newbie at Python and Kivy as well, so please help me.

So I wanted to compile my app to .apk and found a guide video on YouTube.(I'm using Windows btw)

Here it is - https://www.youtube.com/watch?v=D0reWInYl6k&ab_channel=SBDeveloper

So, when I was editing buildozer.spec I noticed that author didn't set the latest KivyMD version, so I did.

And it compiled succesfully, but when I opened it on my phone, it showed the kivy loading screen and then just crashed.

I searched a lot what is the problem but didn't understand anything.

Here is buildozer.spec file:

After compiling a Kivy Application with Buildozer, it crashes on Android when run
