我尝试使用kivy，buildozer
在python中制作简单的Android应用程序代码
from kivy.app import App
from kivy.uix.scatter import Scatter
from kivy.uix.label import Label
from kivy.uix.floatlayout import FloatLayout
class TutorialApp(App):
def build(self):
f = FloatLayout()
s = Scatter()
l = Label(text="Hello!",
font_size=150)
f.add_widget(s)
s.add_widget(l)
return f
if __name__ == "__main__":
TutorialApp().run()
我使用buildozer -v android debug命令制作apk，然后使用adb install <app name>命令安装在Android设备上
adb logcat输出
