【问题描述】：
您好，首先非常感谢在不知不觉中帮助我的所有人。对于像我这样的菜鸟来说，堆栈溢出真的很宝贵。
我是编码新手，学习了 Python3 以了解我是否可以，并尝试为我女朋友的职业活动做一个 Android 应用程序。
我在她的网站上抓取信息，将这些信息放在 JSON 文件中，稍作修改，然后使用 Kivy 和 Float Layout 将它们添加到屏幕上。最先进的部分（对我来说）是在安卓上拨打电话的功能。
在我的 PC（Ubuntu 或 Windows）上一切正常，但在 Android 上，它在启动时崩溃（在“加载”后我得到一个黑屏）。
首先，Buildozer 提出了很多要求（您将在 .spec 文件中看到），在该问题解决后，我在另一个具有 android 权限被拒绝 ACCESS_SURFACE_FLINGER 的情况下运行。我用 builddozer.spec 询问过，这并不像您在日志中看到的那样好。
我还在main.py中使用了一些代码询问
from android.permissions import request_permissions, Permission
request_permissions([Permission.ACCESS_SURFACE_FLINGER])
它会将该权限作为无 ACCESS_SURFACE_FLINGER 参数返回。
你能帮帮我吗？我花了 2 天时间寻找如何让它发挥作用，但我的技能（和谷歌）还不够。
我的 buildozer.spec：
[app]
# (str) Title of your application
title = ConcepTruelle
# (str) Package name
package.name = conceptruelle
# (str) Package domain (needed for android/ios packaging)
package.domain = org.conceptruelle
