使用Buildozer构建APK时遇nest-asyncio模块未找到崩溃问题

以下是针对你遇到的ModuleNotFoundError: No module named 'nest_asyncio'问题的具体解决步骤：

1. 检查buildozer.spec的requirements配置 #

打开项目根目录下的buildozer.spec文件，找到requirements行，确保已正确添加所有依赖，格式应为：

requirements = python3,kivy,nest_asyncio,aiofiles

注意模块名拼写必须完全正确，不要加多余空格或符号；如果指定版本号，要确认该版本在PyPI上有适配Android的轮子包，否则可能导致构建失败或模块无法正常打包。

2. 清理Buildozer缓存后重新构建 #

旧构建缓存可能导致新依赖未被正确打包，执行以下命令清理缓存并重新构建：

buildozer android clean
buildozer android debug deploy run

3. 验证Python环境一致性 #

确保本地开发环境和Buildozer使用的Python环境一致，避免出现本地安装了模块但Buildozer构建时使用的虚拟环境未同步的情况。如果用了虚拟环境，先激活环境再执行构建命令。

4. 手动指定模块源码包（可选） #

如果默认PyPI源无法正确获取nest_asyncio模块，可在requirements中直接指定源码包链接，例如：

requirements = python3,kivy,nest_asyncio@https://pypi.org/packages/source/n/nest_asyncio/nest_asyncio-1.5.6.tar.gz,aiofiles

替换链接中的版本号为最新稳定版即可。
