我正在使用 kivy 构建一个应用程序，它在我的 Linux 笔记本电脑上完美运行。我使用 buildozer 构建 Android 应用程序，并且日志没有显示任何错误。完成后，将在 bin 文件夹中创建 apk 文件。
然后我复制 apk 文件并将其粘贴到我的手机存储中，然后安装该应用程序。
当我打开应用程序时，它显示 kivy 徽标并正在加载......但随后它崩溃了！我尝试了一整天来寻找解决方案，但我无法实现。
我在谷歌搜索问题时找到了这个命令，它应该对调试有帮助，但我无法理解输出！：
buildozer android logcat
这是我运行此命令时打印的日志

此外，我尝试使用此命令运行构建时存储整个日志：
buildozer android debug deploy run logcat > log.txt
这是log文件
此外，以下是我对默认 buildozer.spec 文件所做的更改：
[app]
# (str) Title of your application
title = Overall Translator
# (str) Package name
package.name = overallTranslator
# (str) Package domain (needed for android/ios packaging)
package.domain = org.nidhal.overallTranslator

这是 logcat
的输出Edit2：解决了@inclement 提出的“没有找到模块”错误后，该应用程序仍然在我的 Android 手机上崩溃。这是我运行应用程序时收到的新 logcat

Beautifulsoup4 需要一个 python-for-android 构建配方才能工作，但我认为目前还没有（尽管你的问题似乎更普遍，你根本没有包含它）。
如果有人遇到此问题，我强烈建议使用模拟器进行调试，而不是依赖 logcat。就我而言，logcat 毫无用处。它没有告诉我任何有关错误的信息。
我需要一步一步尝试删除依赖项，直到发现错误。 @inclement 的回答和评论也很有帮助。
