Socket + Buildozer?

Question

Python

I want to send a UDP packet from the APK of the application, but the bulldozer is against it. If you just silently import socket into the code, it will not work, the application will crash. It is possible to work with HTTP, but not with the protocol?

Here's what I've tried and it doesn't work;

requirements = socket

Compiling with Cython
client.cpython-38.so

Used C language, ran inside python.

I got into kivy.network and wrote an additional library.
I tried scapy.all

Here is a person with the same problem, asked a question on github
https://github.com/kivy/buildozer/issues/1121
Interesting, but you can't import aiohttp either?) Somehow stupidly it turns out that socket cannot be imported into the kivy project .

import socket

from kivymd.app import MDApp
from kivy.lang import Builder
from kivy.uix.button import Button

class Send_UDP():
def __init__(self, host='192.168.12.1', port=787):
self.host = host
self. port = port
self.server = (self.host, self.port)
self.sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

def send(self, packet):
self.sock.sendto(packet.encode( "UTF-8"), self.server)

se=Send_UDP()

class Test(MDApp):
def build(self):
se.send('test packet')
button = Button(text='Hello world', font_size= 14)
return button

Test().run()

Compile: buildozer android debug deploy run

I solved the problem! If anyone has bumped into it, here's what to do:
1. requirements = python3,kivy,kivymd
Import ALL python3 modules, including socket. If the module was installed additionally - pip install new_module. Then you need to specify an example - kivymd
2. An error will appear - [Errno 13] Permission denied. And then it dawned on me, you need to remove # android.permissions = INTERNET in buildozer
You need to indicate that your application is needed on the Network, then you can safely use socket
