问候

我是 kivy 的新手，我想使用 buildozer 为 android 编译一个 kivy 应用程序，但 buildozer 无法安装 android ndk。 buildozer 使用的链接已过时，在使用 raspbian 最新版本时不再可用

这是我从 termianl 得到的错误

【问题讨论】：

这看起来像是一个 buildozer 错误，但我认为您会遇到更深层次的问题，即官方 NDK 都不会在 rpi 上运行。

标签： android android-ndk kivy kivy-language buildozer

【解决方案1】：

据我所知，Raspberry PI HARDWARE 不支持它（如果你想你可以尝试使用 RPI），但我不确定 raspbian ，无论如何 buildozer 中的链接是旧的所以你必须在location 自己下载 NDK。然后将 zip 解压缩到以下位置：/home/NAME/.buildozer/android/platform。那么你应该可以在运行命令时进行操作了。
