【问题描述】：
我正在为 Android/iOS 制作 Python3/Kivy 应用程序。它使用beautifulsoup4 从网站上抓取信息（通过一种解决方法来绕过htmlparser 的错误）并使用Kivy 在屏幕上显示它们。我还添加了 4 个按钮，3 个用于社交媒体，一个用于为手机模块提供电话号码。
对于这一部分，我使用 plyer 定义 phonecall() 和 call.makecall() 方法。 这根本不起作用，当我尝试添加该按钮绑定时，我的应用程序在 GNU/Linux 或 Android 上崩溃。你能帮帮我吗？
在我的 main.py 中导入了什么：
import sys
import kivy
kivy.require('1.9.1')
import os
import time
import requests
import webbrowser
from kivy.app import App
from kivy.config import Config
from kivy.uix.widget import Widget
from kivy.uix.label import Label
from kivy.uix.button import Button
from kivy.core.window import Window
from kivy.uix.floatlayout import FloatLayout
from kivy.lang import Builder
import plyer
from plyer import call
import bs4
import jnius
from jnius import autoclass
我在 main.py 上的主类：
class ConceptruelleApp(App):
def build(self):
"""

call.makecall(tel=tel)
