[Krozark]

I'm using kivy and p4a both on develop branch

On android :

audio.start()

You need to give proper permissions in order for the function call to work. In your buildozer.spec add RECORD_AUDIO to the permissions parameter

Hello, I'm new in Python and tried the example of audio code in this github, but it does not work.
Have you solved this yet? because when I checked the buildozer.spec already had RECORD_AUDIO in it.

you need to ask the permition at runtime + compilation (in .spec)

[Watha2]

Permission has already exists in .spec
I'm sorry, since I'm a novice in Python, if you don't mind, could you tell me how to ask permission at runtime?
How did you write the Python code for it?

Thank you

[Krozark]

in you .spec:

# (list) Permissions
android.permissions = RECORD_AUDIO

in your main.py file

if __name__ == "__main__":
 # ... some code
  if platform == "android":
      from android.permissions import request_permissions, Permission
      request_permissions([
          Permission.RECORD_AUDIO,
         # .... other permission
      ])
  # ... other code
