Apk file build using buildozer closes as soon as i open it

Question

I try to make a simple hello world app for android using python, kivy and buildozer.

my hello.py file is

from kivy.app import App
from kivy.uix.button import Label
class Hello2App(App):
    def build(self):
        return Label()
if __name__=="__main__":
    Hello2App().run()

My hello.kv file

<Label>:
text: 'Hello World!'

I use buildozer in ubuntu to compile apk. Sudo buildozer android debug deploy

do i need to apply looping like we do in pygame and Tkinter to show gui or window

Did you enable Kivy in your buildozer spec? What commands did you run? — masnun, Aug 20 '16 at 16:51
Did you mean `buildozer android debug deploy`? Try using `android_new` instead of `android` — masnun, Aug 21 '16 at 19:08

Your Python script must be named main.py. If you check the error that you are getting it would read something like "Unable to find main.py". Just try renaming the file from hello.py to main.py and build again.

Done. but still same result. – Shobhit Bhatnagar Aug 21 '16 at 14:15
Try using this command instead to see what error you get exactly. `buildozer android debug deploy run logcat` – Mohamed Ali Aug 21 '16 at 17:40

I fixed your error by changing main.py:

from kivy.app import App
from kivy.lang import Builder


class Hello2App(App):
    def build(self):
        return Builder.load_file("hello.kv")


if __name__ == "__main__":
    Hello2App().run()

hello.kv:

Label:
    text: 'Hello World!'

Now you just need to type buildozer init and buildozer android debug and you are ready to go.
