Debian – Python Kivy & Buildozer : How remove the Kivy logo and message "loading …"

I’ve built a little application that works just as well on PC as it does on Android (nothing complicated; the application is excessively simple).

Everything works fine on my android and on my debian and windows. On the other hand, I have an esthetic problem on Android.

When I launch the application, it displays the Kivy logo and a “loading …” message.

I’m in the latest version of buildozer, kivy and python and while searching on Google (old articles) I’m told that I need to change the buildozer.spec file but none of the proposed solutions work.

Do you have any ideas? Is it still possible?

    Ok I found the solution (I'm stupid ^^ )

    Here are the actions I've follow

    • open the buildozer.desc
    • add presplash.filename = yourfile.png (and not presplash.file as I've done since days ... you know why I'm stupid now)
    • add android.presplash_color= black (or any color you want)

    and compile ...

    Sorry for my stupid questions :(

    Customize Splash Screen (Optional): If you want to create a custom splash screen, you can create a new layout and use it to display your logo or message while the app initializes. For example, you can use Kivy’s ScreenManager to control this behavior. Here’s a simple example:

    from kivy.app import App
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.uix.image import Image
from kivy.uix.label import Label
from kivy.clock import Clock

class SplashScreen(Screen):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        # Add a custom image or message to the splash screen
        self.add_widget(Image(source='your_splash_image.png'))
        Clock.schedule_once(self.change_screen, 3)  # Wait 3 seconds before changing screen

    def change_screen(self, dt):
        self.manager.current = 'main_screen'

class MainScreen(Screen):
    pass

class MyApp(App):
    def build(self):
        sm = ScreenManager()
        sm.add_widget(SplashScreen(name='splash'))
        sm.add_widget(MainScreen(name='main_screen'))
        return sm

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

    This code shows a custom splash screen for 3 seconds before transitioning to the main screen.

    Rebuild the Application: After making the changes to the buildozer.spec file, you need to rebuild the application by running:

    buildozer android debug

    This should remove the Kivy logo and "loading…" message or allow you to customize the startup screen.
