main file and buildozer

[Robert]

I took a quick look at your code, I did not try to run it (I never debug anybody's code), so I don't know if these are the cause of your issue:

- The permissions use is duplicated, and the first use is a problem. https://github.com/Android-for-Python/Android-for-Python-Users#user-permissions

- requirements has two issues (I don't know if there are more):

charset-normalizer will give this error https://github.com/Android-for-Python/Android-for-Python-Users#em_x86_64-instead-of-em_aarch64

'permissions' seems to be an invention of yours.

yeah i tried on this and i getting the same problem

there any possiblities to solve this crash

[Robert]

One of the above users, got this workaround on Discord.
Add this code at the very top of your main.py

import os
from kivy.utils import platform
if platform == "android":

     os.environ["SDL_AUDIODRIVER"] = "android"

Sorry I don't know anything about this one.

When you have an issue always show lots of lines of the log (as a .txt file) it can't be too many, this is too few, because context is important for somebody reading it.

[IIoT 4.0]

yeah ok sir but this crash is happening for one or two videos other videos playing superb
