"Kivy 应用无法在安卓手机上启动"

Question

我正在制作一个简单的应用程序，以便（将来）从网页中查看一些内容。 目前它在 Windows 上完美运行（它登录并提供一个新页面）。但它停止在我的手机上运行。 它不会使用 kivy 启动器启动。 它不能太大。 我不知道是什么问题。 我已经尝试了一切......这是我的代码：

Answer 1

您应该按照kivy文档中的调试说明进行操作，如果不能明确给出答案，请将logcat输出粘贴到此处。

Answer 2

我过去有同样的问题，我通过在 .spec 中添加要求来解决

这个要求对我有用：

requirements = hostpython3==3.7.8,python3==3.7.8,kivy==1.11.1, certifi,chardet, lxml, docutils, future, idna, Kivy-Garden, Pygments, requests, six, soupsieve, urllib3, deep-translator, arabic-reshaper, python-bidi, openssl, pyopenssl, numpy, pytz, python-dateutil, pandas, setuptools, zope.interface, datetime
