an immature kivy user : desire to make an android recorder with pyjnius package

Versions

Python : 3.10
Buildozer : 1.0

Description

AS an immature kivy user, I want to make a recorder , with ''record'' and '' stop record" button, designed by kivy.uix package. However, android.permissions set and code seem to be in trouble.

test platform

android 8.0.0

# check permission granted or not
write_permission = permission.WRITE_EXTERNAL_STORAGE

read_granted = PackageManager.PERMISSION_GRANTED == PackageManager.checkPermission(read_permission, context.getPackageName())
record_granted = PackageManager.PERMISSION_GRANTED == PackageManager.checkPermission(record_permission, context.getPackageName())

# give permission if not granted
if not write_granted or not read_granted or not record_granted:
    permissions = [write_permission, read_permission, record_permission]
    requestCode = 0                                                                                             # Request code for requesting permissions

        # button '' stop play ''
        play_stop = Button(text='stop Play', size_hint=(1, 1 / 4))
        play_stop.bind(on_press=self.stop_playing)
