android-IOError：[Errno 2]没有这样的文件或目录：u’/…/ RetroApp-debug.apk’
作者：互联网
我是kivy库编程的初学者,但是我已经完成了非常简单的应用程序,例如Kivy教程中的.在桌面上,它很酷.但是比我想做的.apk文件(还没有使用过Linux).我已经尝试了很多步骤来制作.apk文件,但是最后,当我安装并打开该程序时.它有一个错误.我尝试了很多规格和new_android,但没有任何效果.最终,我将buildozer更新到了最新版本.但是现在,在buildozer android调试之后,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.

请帮我！

解决方法:
请按照以下步骤更改您的Python脚本：
main.py
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克隆https://github.com/kivy/buildozer
cd buildozer
python setup.py构建
sudo pip install -e.
>在某处下载并提取Crystax NDK(〜/ opt /是一种选择)：https://www.crystax.net/en/download
>在buildozer.spec中指定以下内容：
buildozer.spec
需求= python3crystax,kivy
android.ndk = 10.3.2
android.ndk_path = /opt/crystax-ndk-10.3.2
