Black screen after presplash screen

[satyam yadav]

I have used lottie file in presplash screen which works fine but after it a black screen appears for some time and then my first screen of app gets open , why i am getting this behaviour (i dont want this black screen i just want my pre splash screen and then my usual app screen and how i can achieve it.

And other question is that app does not fit full to the screen even  i have set it to the fullscreen = 1 in bulldozer.spec file.

I don't know anything about your first question.

Or about fullscreen option

 🤣

However here is how I conditionally remove the status bar https://github.com/Android-for-Python/c4k_photo_example/blob/main/main.py#L20-L30

Set the icon and splash screen like this:

# (str) Presplash of the application
#presplash.filename = %(source.dir)s/data/presplash.png
presplash.filename = chart.jpg

# (str) Icon of the application
#icon.filename = %(source.dir)s/data/icon.png
icon.filename = chart.png

Remember to 'buildozer appclean' after the change and before the next build.

If you have a problem check that the image file types are supported for the case.

For more control of the presplash use lottie files

# (string) Presplash animation using Lottie format.
# see https://lottiefiles.com/ for examples and https://airbnb.design/lottie/
# for general documentation.
# Lottie files can be created using various tools, like Adobe After Effect or Synfig.
#android.presplash_lottie = "path/to/lottie/file.json"

I  referred this answer of yours for android_prespalsh_lottie but then for some time screen gets black and afterwards the app functions starts so i am asking that how i can remove the black screen , you can see the video i attached in above question

The last line of my earlier post (which you failed to quote) said:

>  I have no experience using lottie files.

Which explains my answer above.

The first question I think you need to check the build function of your App class, if the build function need to do a lot time costed task before it return, it will show you a black screen before you main widget showed.
