Kivy example does not build

[FilMarini]

• Python version: 3.10.12
• Operating System: Ubuntu 22.04
• BlueZ version (bluetoothctl -v) in case of Linux: 5.64

Description

I tried to build the kivy example for Android. An error pops up not allowing to finish the build

What I Did

Following the README, I tried to build the kivy example.

This is what I did

pip3 install buildozer cython
buildozer android debug

And this is what I get (after a while)

I tried running it from both the develop branch as well as from the latest tag, v0.22.3, and master

[FilMarini]

The error is related to this line: https://github.com/hbldh/bleak/blob/develop/bleak/backends/p4android/recipes/bleak/__init__.py#L11

if you change it to 0.20.0 for example, buildozer finishes the build.

Unfortunately, if I run the compiled example on my phone, the app crashes at start.
Reading the log, it seems that a significant error could be this one:

FATAL EXCEPTION: main

Any idea how to solve this?
Thanks
