Question

在Android上注意到Kivy应用的以下问题。示例代码取自Kivy Basic documentation：

from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.label import Label
from kivy.uix.textinput import TextInput


class LoginScreen(GridLayout):

    def __init__(self, **kwargs):
        super(LoginScreen, self).__init__(**kwargs)
        self.cols = 2
        self.add_widget(Label(text='User Name'))
        self.username = TextInput(multiline=False)
        self.add_widget(self.username)
        self.add_widget(Label(text='password'))
        self.password = TextInput(password=True, multiline=False)
        self.add_widget(self.password)


class MyApp(App):

    def build(self):
        return LoginScreen()


if __name__ == '__main__':
    MyApp().run()

我正在使用新的P4A工具链（$buildozer -v android_new debug deploy run）。这是我构建应用程序的配置：

Python：2.7.6
Kivy：1.9.2
buildozer：0.33dev

该应用运行正常，但只要输入任何数字(0-9)就会崩溃。字符(a-z)，即使是特殊字符，也能完美运行。在桌面上没有问题（Ubuntu 14.04）。

这在Android 6.0.1和Android 5.1.1（单独的设备）上都经过测试。

这是$adb logcat|grep python的输出（仅限最后几行）：

在这方面的任何帮助将不胜感激。
