【问题描述】：

我尝试使用 buildozer 构建一个 apk 文件 - （我使用名为 main.py 的 py 文件创建了一个单独的文件 buildozer.spec - 我在 Ubuntu 下运行了该构建）

但是当我跑步时：

buildozer -v android debug

运行命令后出现以下错误 （它可以工作一段时间，但最后我收到此错误消息并且未创建 apk）

这是我要转换的文件：

import kivy

from kivy.app import App
from kivy.lang import Builder
from kivy.config import Config
from kivy.core.window import Window

Window.size = (800,230)

from kivy.uix.boxlayout import BoxLayout

class LblTxt(BoxLayout):
    from kivy.properties import ObjectProperty
    theTxt = ObjectProperty(None)

class MyApp(App):
    def build(self):
        self.root = Builder.load_file('simpleForm.kv')
        return self.root

if __name__ == '__main__':
    MyApp().run()

为什么无法构建 apk 文件？

【参考方案1】：

问题

查看日志，没有太多信息，但我可以从中假设您在 Windows 上使用 WSL 或类似的东西，而不是使用实际的 Ubuntu 设备。 buildozer 不起作用的原因，我不知道，日志没有回溯到足以让我找出来，但很可能是因为 WSL 不是一个成熟的 Linux 发行版

解决方案

我的解决方案是使用名为Google Colaboratory的在线虚拟机

在弹出窗口中按取消以打开一个新笔记本

按页面右上角的连接初始化虚拟机

然后按+代码

添加一个新的代码单元

要设置 buildozer 和其他命令，请粘贴到单元格中并按播放图标

!pip install buildozer
!pip install cython==0.29.19
!apt install -y \
    python3-pip \
    build-essential \
    git \
    python3 \
    python3-dev \
    ffmpeg \
    libsdl2-dev \
    libsdl2-image-dev \
    libsdl2-mixer-dev \
    libsdl2-ttf-dev \
    libportmidi-dev \
    libswscale-dev \
    libavformat-dev \
    libavcodec-dev \
    zlib1g-dev
!apt install -y \
    libgstreamer1.0 \
    gstreamer1.0-plugins-base \
    gstreamer1.0-plugins-good
!apt install build-essential libsqlite3-dev sqlite3 bzip2 libbz2-dev zlib1g-dev libssl-dev openssl libgdbm-dev libgdbm-compat-dev liblzma-dev libreadline-dev libncursesw5-dev libffi-dev uuid-dev libffi6
!apt install libffi-dev
!pip install kivy
!apt install ldd

然后将您的文件上传到文件页面

制作另一个单元格并运行!buildozer init

通过右键单击并刷新来刷新文件屏幕

根据需要打开和编辑buildozer.spec 文件

最后，创建一个新单元并运行 !buildozer -v android debug 并等待它完成，您可能需要在途中接受一些许可证

完成后，再次刷新文件页面，然后导航到现在应该出现的 bin 目录，点击 apk 的三个点，然后点击下载
