使用 Kivy 打包 APK，您需要遵循以下步骤：
1. 安装 Kivy 和 Buildozer
您需要运行以下命令来安装 Kivy 和 Buildozer：
```
pip install kivy
pip install buildozer
```
2. 创建一个 Kivy 应用程序
创建一个 Kivy 应用程序，并确保它可以在本地计算机上运行。
3. 配置 buildozer.spec
文件
在您的 Kivy 应用程序目录中创建一个名为 buildozer.spec 的
文件，并配置以下选项：
```

您需要根据您的应用程序进行相应的更改。
4. 创建一个虚拟
环境
在您的项目目录中创建一个虚拟
环境：
```
python3 -m venv myenv
```
5. 激活虚拟
环境
激活虚拟
环境：
```
source myenv/bin/activate
```
6. 初始化 buildozer
初始化 buildozer：
```
buildozer init
```
7. 编辑 buildozer.spec
文件
编辑 buildozer.spec
文件，并确保您已经配置了正确的选项。
8. 打包 APK
运行以下命令来打包 APK：
```
buildozer -v
android debug
```
这将创建一个名为 myapp-0.1-debug.apk 的 APK
文件。
注意：在打包 APK 之前，请确保您已经按照 Kivy 官方文档中的说明正确地配置了
Android SDK 和
NDK。
本文介绍了一个在AndroidStudio中遇到的奇怪问题：新增的cpp文件无法被编译，错误也无法被检测到。通过删除工程目录下特定的debug和release文件夹并重新同步及清理工程，成功解决了cpp文件的编译问题。
后面直接把工程目录XXX\app\.externalNativeBuild\cmake下的debug和release两个目录删掉后，然后同步及清理工程后就可以build新加的cpp文件了。
