问题原因 #

unzip是Linux系统中用于解压ZIP压缩文件的命令行工具，你的WSL环境未安装该工具，导致Buildozer在解压Android NDK压缩包时失败。

解决步骤 #

在WSL终端中执行对应命令安装unzip：

• 若使用Ubuntu/Debian系发行版：

sudo apt update && sudo apt install unzip -y

• 若使用Fedora/RHEL系发行版：

sudo dnf install unzip -y

安装完成后，重新运行Buildozer打包命令即可。

音频文件打包补充提示 #

虽然本次错误与音频文件无关，但打包时需确保connection_voice.ogg被正确纳入APK。可在项目的buildozer.spec文件中添加以下配置：

# 包含指定格式的资源文件
source.include_exts = py,png,jpg,kv,atlas,ogg
# 或直接指定单个文件
source.include_files = connection_voice.ogg
