如何在 ARC Welder 下调试 Kivy 应用程序
How to debug a Kivy application under ARC Welder
为了在 Windows 下调试我的 Python Kivy 应用程序，我下载了 ARC Welder 工具并将其安装在 Chrome 浏览器下的 Windows 下。安装工作正常，加载我的 .apk 文件也很好，该文件是使用 Buildozer 工具在 Boot2Docker、Docker、Ubuntu 下构建的。 Chrome 应用程序显示 Kivy 徽标，然后告诉 "loading" 后跟一个“:-(”图标。
我如何启动日志文件来显示导致 Kivy 应用程序崩溃的 运行 时间错误？
在 Chrome 控制台显示的消息下方：

问候，
欢迎提供有关 ARC Welder 上 Kivy 调试程序的指导。
在最后一个带有“:-(”图标的错误屏幕上，右键单击鼠标并选择 select "inspect" 或 "inspect background"。我已经找出了问题的根本原因错误，这是将 ffmpeg 模块和编解码器添加到 buildozer 环境的必备条件。我在 Ubuntu 14 系统映像中安装了 ffmpeg 包，并使用以下命令将其添加到 buildozer.spec 要求中声明：requirements = kivy,ffmpeg。这解决了问题，.apk 开始播放媒体，在 ARC Welder 浏览器平台下，以及在 Android 下 6. 对解决方案感到满意，ARC Welder 正在运行完美！
