【问题描述】：
我想将我的 python 脚本编译为 APK 并在 Android 上运行。我正在使用 kivy、os、pika、threading 和自己的模块“RabbitMQ”。
Lubuntu 18.04 和 Python 3.6
对于代码，我使用 Python 3.7。
在 buildozer.spec 我有 requirements = python3,kivy,RabbitMQ 和 android.permissions = INTERNET。
当我在 Android 上运行我的应用时，它开始加载，然后就崩溃了。
这是我的 logcat 日志：

【问题讨论】：
-
这个错误很奇怪，说明找不到某个java类但是这个java类应该存在，我不明白为什么这个小东西会随机失败。
-
如果你做了一个简单的构建，只运行 kivy 并且没有额外的要求，那行得通吗？
-
是的。当我构建简单的 Hello World 时，它工作正常
-
有趣，我真的不知道为什么会这样。如果您从头开始重新构建，它会以同样的方式失败吗？
-
我删除了所有 buildozer 文件，重新构建，但仍然出现此错误。
