[AmjdAlhashede]

Permissions Involved

The following Android permissions may be required based on the action:

• READ_EXTERNAL_STORAGE → Required on Android <= 12.
• WRITE_EXTERNAL_STORAGE → Required only for Android <= 10.
• WRITE_SETTINGS → Required to change system ringtones.
• READ_CONTACTS / WRITE_CONTACTS → Required for setting contact-specific ringtones.

The library should handle permission logic based on SDK version and requested operation.
