Webbrowser尝试在浏览器中打开PDF文件而不是html

Question

我正在尝试使用webbrowser模块在kivy应用程序中使用Python在浏览器中打开文件。 这是我的代码：

import webbrowser
import os

from kivy.app import App

from kivy.uix.button import Button

class SimpleBrowserApp(App):
    def build(self):
        btn = Button(text="open browser")
        btn.bind(on_press=SimpleBrowserApp.OpenBrowser)
        return btn

def OpenBrowser(*args):
    webbrowser.open("file:///" + os.getcwd()+"/"+"map.html")

SimpleBrowserApp().run()

当我尝试打开它时，我的手机会返回它-(PDF inaccessible(" map.html" can't open)):。

我的“ map.html”与“ main.py”位于同一文件夹中。

buildozer.spec：

也许我听不懂，或者还有另一种在浏览器中打开HTML代码的方法。 我只需要在浏览器中打开此文件。
