【问题描述】：
我在 Ubuntu 上使用 kivy v1.10.1、buildozer 0.39 和 python 3.5.2。
我有一个非常基本的 kivy 应用程序
from kivy.app import App
from kivy.uix.screenmanager import Screen
from kivy.uix.button import Label
from kivy.lang import Builder
root = Builder.load_string('''
<MainFrame>:
Label:
text: 'Hello world'
''')
class MainFrame(Screen):
def __init__(self, **kwargs):
super(MainFrame, self).__init__(**kwargs)
class BasicApp(App):
def build(self):
return MainFrame()
if __name__ == '__main__':
BasicApp().run()
buildozer 规范包括：
requirements = python3, kivy
我可以使用 buildozer 构建 APK，但是当我在 android 设备上运行它时，它似乎会加载，但随后会停止。
这似乎是 logcat 输出的相关部分

谁能指出问题的可能根源？
【问题讨论】：
-
发布应用程序启动和崩溃之间的完整 lgocat 输出。您也可以只删除包含字符串
python的行来缩小搜索范围。 -
@inclement 我已将 logcat 输出粘贴到 justpaste.it/7hge7
-
不幸的是，我没有看到任何明显的错误 - 加载 libpython2.7.so 时似乎存在问题，但这甚至不应该发生。您可以粘贴完整的 logcat 而不限制包含
python的行吗？这可能是一个较低级别的问题，我们必须关心 Python 进程本身以外的其他内容。 -
@inclement 这里是完整的 logcat ge.tt/2CRlJrx2
-
奇怪的是它正在尝试加载 libpython2.7。你能发布你的
buildozer.spec文件吗？
