[英]Kivy Buildozer: AttributeError: 'NoneType' object has no attribute 'text'
i am testing Kivy with Buildozer to make an small app for my Android Device.我正在使用 Buildozer 测试 Kivy,以便为我的 Android 设备制作一个小应用程序。 On my PC everythink is running correctly.在我的电脑上,everythink 运行正常。 But when i want to create the APK with Buildozer everytime i get the Error AttributeError: 'NoneType' object has no attribute 'text'
但是,当我每次收到错误AttributeError: 'NoneType' object has no attribute 'text'
时,我都想使用 Buildozer 创建 APK
I googled a lot of times, but i could not find an answer to my question.我用谷歌搜索了很多次,但我找不到我的问题的答案。
Does anyone has a hint for me?有人对我有提示吗?
Would be great.会很好。
Thank You!谢谢你!

Hi thank you for your fast reply.您好,感谢您的快速回复。 I changed this things and now i get an new Error我改变了这些东西,现在我得到一个新的错误
attributeerror 'super' object has no attribute '__getattr__' kivy
i googled and edited my super.init to super(ConnectPage, self).__init__(**kwargs)
but this error still occurs.我用谷歌搜索并将我的 super.init 编辑为super(ConnectPage, self).__init__(**kwargs)
但这个错误仍然发生。
