Plyer notification not working on android

[CSVStorage]

I'm trying to code a simple application that receive a message and display a notification, everything works fine except the notification.
I run the app on android 10

The code I use for the notification is:

from plyer import notification
notification.notify(title="Notification", message=message)

and I get this error when I run the app on my phone (adb logcat):

'P4A_NUMERIC_VERSION': 'None', 'P4A_MINSDK': '21', 'LC_CTYPE': 'C.UTF-8'})

#    You can define all the "list" as [section:key].

#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

I really cannot understand what's wrong, can someone help me?

Hello! I don't have a solution :/ do you maybe know how to fix this error now?
Thank you!

[EternityForest]

I am also affected by this issue!

[YariKartoshe4ka]

I can suggest this patch

import jnius
original_autoclass = jnius.autoclass
def patched_autoclass(clsname, *args, **kwargs):
    return None if clsname.endswith('R$drawable') else original_autoclass(clsname, *args, **kwargs)
jnius.autoclass = patched_autoclass

import plyer

Of course it is not a good decision, but it works if you does not create notification with image

Hello! I don't have a solution :/ do you maybe know how to fix this error now? Thank you!

Hope this solution to send Android notifications using Plyer can be helpful to someone:
https://github.com/NikitaKokarev/PlyerNotification
I changed the plyer notification logic depending on api_version >= 31.

[Zen-CODE]

Nice, thanks :-)
