I've written a very simple script within kivy using selenium. from kivy.uix.button import Button from kivy.uix.floatlayout import FloatLayout from kivy.app import App from selenium import webdriver class KivyButton(App): def update(self,instance,*args): driver = webdriver.Chrome() driver.get('https://google.com') def build(self): self.layout = FloatLayout(size=(300,300)) self.mybtn=Button(text='Enter',on_press=self.update,pos=(500,300),size_hint=(.1,.1)) self.layout.add_widget(self.mybtn) return self.layout KivyButton().run() It's basically just a button that when you click it, takes you to google.

There are multiple chromedrivers with different versions, and thus the only thing I can think of is the chromedriver version installed by buildriver is not compatible the Chrome version on my phone? But outside of this, I don't know why I am receiving this error. Continue reading...
