java - Kivy 应用程序崩溃，没有非静态方法 openAPKExpansionInputStream

Question

在过去的一周左右的时间里，我一直在绞尽脑汁地思考这个问题，真的需要一些帮助。我的 apk 构建良好，并且在 Linux 上运行 main.py 可以完美运行，但是，当在我的 Galaxy s6 上运行 apk 时，它在打开后不久就崩溃了。我已经尝试更新 buildozer、kivy，确保所有依赖项都已满足并包含在规范文件中(如下)。以及尝试无数其他解决方案，例如更改 api、更新所有构建工具等。

大家有什么想法吗？这是 logcat 的链接，

https://gist.github.com/anonymous/8d571dc4fdcd128087f90902ee702d34

它指示致命信号 6 错误，以及 JNI 错误(复制如下)，但我不确定它们在这种情况下到底与什么相关。无论如何，我不太精通编程，因此我们将不胜感激。

#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

任何帮助都会非常有用

Answer 1

我也遇到了这个错误，并且花了很长时间才找到它。它来自 Window.set_icon("path/to/icon.png") 方法。

from kivy.core.window import Window
Window.set_icon("graphics/icon.png")

当我注释掉这个错误后，错误就消失了。使用之前的 android 工具链和 buildozer (android_old) 没有出现任何问题，但当我们切换到新的“android”目标时就会出现问题。这是一篇旧帖子，但只是将其放在那里以防有帮助......:-)
