Unfortunately [app-name] has stopped !

[Bachir El Khadir]

Hello,

I am trying to build a simple application and deploy it to my android phone (s6). The build process works just fine, but the app crashes on my phone as soon as I open it.

Here is the code for the application:

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()

I have attached the log for the build process ( buildozer android debug ) and for  the deploy(buildozer android deploy run logcat).

Any help is welcome!

For some reason the log for the deploy was not uploaded, I have attached it to this response.

I'm running into essentially the same problem. It's been several months since the poster's question. Any tips on what this is?

I was able to find the error in the android log, below.

Looks like the math library "-lm" isn't linked into the Python shared library.

Ok, how can I fix that? I'm using buildozer android debug to build.

[Bill Janssen]

Don't know enough about either buildozer or android to be able to tell you, sorry.

You might try to find the link line in your buildozer build log and post it, though.
