python-for-android | Turn your Python application into an Android APK

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 have just seen that support for AAB files have just been introduced in Python for Android (p4a). Considering that, fom August 2021, new apps are required to publish with the Android App Bundle on Google Play, this is a crucial addition for any Python dev working on Android apps.

Since I'm currently using Buildozer via Docker, I'd like to know which are the steps to make it generating an .aab instead of (or along to) the traditional .apk

For the sake of clarity, here is what I use to run Buildozer from inside a container (using Docker for Windows) to make the .apk file:

I'm making a cryptocoin app with my friends and i used to make app with python until i got several error on buildozer and python-for-android for days. I can't build apk so i decided to switch to kotlin and curious about something. This app will run with help of a python bot which is running on a server. Can i connect a python server with kotlin client and dump json data sended from python server?

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:
