我正在尝试从firefox android浏览器复制文本，触发一个意图并读取系统剪贴板但是徒劳无功。
firefox webextension副本的剪贴板是否与Android系统剪贴板不同？ 如果是这样，还有其他方法吗？
此外，有什么方法可以将大型blob数据从浏览器传输到应用程序。我目前通过意图uri传递它。

在我看来，import Tkinter as tk
from tkFileDialog import askopenfilename
from Tkinter import *
import pandas as pd
import ttk
import subprocess
# Import all graph codes.
import graph_1
import graph_2
import graph_3
import graph_4
def import_csv_data():
global v
csv_file_path = askopenfilename()
print(csv_file_path)
v.set(csv_file_path)
df = pd.read_csv(csv_file_path)
def openfile():
subprocess.call(['notepad.exe', 'C:/help.txt'])

graph_4.display_graph(v.get())

的剪贴板与android的不同。我可以告诉它，因为我使用firefox应用，它也会显示从Clip Stack复制的文字。这个应用程序是开源的，也许您可以通过查看its code找到如何处理您的案例。
