我是kivy库编程的初学者，但我做了非常简单的应用程序，就像在Kivy教程中一样。在桌面上它很酷。但是我想做.apk文件（没有使用Linux）。我已经尝试了很多步骤来做一个.apk文件，但最后我安装并打开了这个程序。它有一个错误。我已经尝试了很多规格和new_android，但没有任何效果。最后我将buildozer更新到最后一个版本。但现在，在buildozer android debug之后，他写了这个错误：
IOError：[Errno 2]没有这样的文件或目录：u'/ home / kivy / reyyy / .buildozer / android / platform / build / dists / RetroApp / build / outputs / apk / RetroApp-debug.apk'。

请帮帮我！ 瓦迪姆。

请更改您的Python脚本，如下所示：
class PongGame(Widget):
...
def __init__(self, **kwargs):
super(PongGame, self).__init__(**kwargs)
...
def retry(self):
由于您使用的是Python 3.x，因此需要执行以下操作：
使用python3支持安装Buildozer
git clone https://github.com/kivy/buildozer
cd buildozer
python setup.py build
sudo pip install -e。
在某处下载并解压缩Crystax NDK（〜/ opt /是一个选项）：https://www.crystax.net/en/download
