please help with plyer library in kivy

[Fredy Pichihua oscco]

hello! I'm trying to implement voice recording for android and I'm working with the PLYER library but it doesn't seem to work. I'm trying to test with the library but I get an error like the following:

from kivy.app import App

from kivy.lang import Builder

from kivy.properties import NumericProperty

from kivy.properties import ObjectProperty

from kivy.uix.boxlayout import BoxLayout

Builder.load_string('''
