android - kivy：来自 buildozer 的 apk 在 android 中不起作用

Question

我通过 buildozer 制作了一些公交信息应用程序，我正在测试该应用程序。

从 buildozer 构建的 apk 成功。

手机：三星 S7 Edge (Android 7.0)

操作系统：Ubuntu 18.04.1 LTS

我从 buildozer 获得了 apk 文件；在我的 S7 edge 中安装并启动它。我的桌面没有问题，但应用程序崩溃了。当我打开应用程序时，它会立即熄灭。我花了将近三天的时间，但我找不到解决方案。这里有解决方案吗？感谢您的阅读。

#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    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
