Question

我正试图在我的nexus 5上的kivy启动器中从kivy.org运行此代码。我在kivy文件夹和“android.txt”文件中创建了一个文件夹。这是main.py：

import kivy
kivy.require('1.9.0')
from kivy.app import App
from kivy.uix.label import Label


class TestApp(App):
   def build(self):
          return Label(text='Hello World')
if __name__ == '__main__':
   TestApp().run()

当我从启动器启动时，它会立即崩溃。这就是我在日志文件夹中获得的内容：

[INFO              ] Logger: Record log in /storage/emulated/0/kivy/myshit/.kivy/logs/kivy_15-05-01_6.txt

[WARNING           ] stderr:     class TestApp(App):
[WARNING           ] stderr: NameError: global name 'Label' is not defined

请指导我做错了什么？附：我不编译应用程序，我只是想在启动器中运行它。示例游戏和展示工作正常。
