如何解决Plyer通知在Android上不起作用
我正在尝试编写一个简单的应用程序，以接收消息并显示通知，除该通知外，其他一切都正常。
此外，如果我在Windows上运行该应用程序，则可以正确显示通知
我在android 10上运行该应用程序
我用于通知的代码是：
from plyer import notification
notification.notify(title="Notification",message=message)
当我在手机（adb logcat）上运行应用程序时收到此错误：
'P4A_NUMERIC_VERSION': 'None','P4A_MINSDK': '21','LC_CTYPE': 'C.UTF-8'})
