Python 在kivy中推送通知

我计划使用kivy开发一个与我的一个项目相关的应用程序。但我仍然找不到一种方法让应用程序在后台运行，当满足一定条件时，我需要它在手机上显示推送通知。如何在kivy中添加推送通知功能？请让我知道，如果有人知道如何使它工作。（注意-即使应用程序在移动设备中关闭，也应该在后台运行。）

我不能告诉你如何在后台运行（因为我也不知道），但我可以告诉你如何通知

顺便说一下，plyer在android上的运行不如windows，所以您应该使用java lib jnius

代码如下：

from kivy.app import App
from kivy.uix.button import Button
from jnius import autoclass

def notify(*args):
    AndroidString = autoclass('java.lang.String')
    PythonActivity = autoclass('org.kivy.android.PythonActivity')
    NotificationBuilder = autoclass('android.app.Notification$Builder')
    Context = autoclass('android.content.Context')
    Drawable = autoclass('org.test.notify.R$drawable')
    icon = Drawable.icon
    notification_builder = NotificationBuilder(PythonActivity.mActivity)
    notification_builder.setContentTitle(AndroidString('Title'.encode('utf-8')))
    notification_builder.setContentText(AndroidString('Message'.encode('utf-8')))
    notification_builder.setSmallIcon(icon)
    notification_builder.setAutoCancel(True)
    notification_service = notification_service = PythonActivity.mActivity.getSystemService(Context.NOTIFICATION_SERVICE)
    notification_service.notify(0,notification_builder.build())

class NotifyApp(App):
    def build(self):
    return Button(text="notify", on_press=notify)

if __name__ == '__main__':
    NotifyApp().run()

---

如果您不断出现错误，请看
