大家好，首先非常感谢所有在不知情的情况下帮助我的人。对于像我这样的人来说，堆栈溢出真的很珍贵。
我刚开始编程，学习了Python3，看看是否可以，并试图为我女朋友的职业活动开发一个Android应用程序。
我在她的网站上抓取信息，把它们放在JSON文件中，对它们进行一些修改，然后使用Kivy和Float Layout将它们添加到屏幕上。最高级的部分(对我来说(是在android上打电话的功能。
所有这些在我的电脑(Ubuntu或Windows(上都运行得很好，但当它进入Android时，它在启动时崩溃(在"加载"后，我会出现黑屏(。
首先，Buildozer询问了很多需求(你会在.spec文件中看到(，在这个问题解决后，我在另一个被拒绝ACCESS_SURFACE_FLINGER的android权限下运行。我询问了builddozer.spec，但这并不像你在日志上看到的那样好。
我还在我的main.py 中使用了一些代码来询问
from android.permissions import request_permissions, Permission
request_permissions([Permission.ACCESS_SURFACE_FLINGER])
并且它将该Permission作为无ACCESS_SURFACE_FLINGER参数返回。
你能帮我一把吗？我花了两天时间寻找如何让它发挥作用，但我的技能(和谷歌(还不够。
