我已经用Kivy制作了Kivy应用程序，并且我想制作一个apk，因此我按照Kivy网站https://kivy.org/doc/stable/guide/packaging-android.html#buildozer的说明尝试使用buildozer。它不起作用，所以我读了很多关于它的论坛，但是没有人回答我，所以我尝试了其他构建过程，但是它们也没有起作用。错误似乎所在的日志是：

使用~/.buildozer/android/platform/android-sdk-20/tools/android，我在许多论坛上看到了Android SDK构建工具20，
我在main.py中导入json，会导致错误吗？
您能帮我吗，我开始失去希望...
