Reading/writing text file in an android

[vishnu-rvb]

Question

I am trying to test flet for reading and writing a text file place inside a directory of my choice , but i seem to get permission errors , any advice on this?
For this i have created a directory in my android phone '/system/storage/emulated/0/test/test.txt'

Code sample

import flet as ft
import time
import os

def main(page: ft.Page):
    #writing from user input
    writeTxt = ft.TextField(hint_text='enter text to write')
    errorTxt =ft.Text('')
    directoryTxt=ft.TextField(hint_text='enter location')
    def write(e):
        print('write called')
        try:
            f=open(directoryTxt.value,'w')
            f.write(str(writeTxt.value))
            f.close()
        except Exception as e:errorTxt.value=str(e)
    btn=ft.ElevatedButton('write',on_click=write)
    page.add(writeTxt,directoryTxt,errorTxt,btn)

    #contineous reading from file
    readTxt = ft.Text('text')
    cwdTxt = ft.Text(os.getcwd())
    try:
        os.chdir(r'/system/storage/emulated/0/')
    except Exception as e:errorTxt.value=str(e)
    page.add(readTxt,cwdTxt)
    while True:
        try:
            f=open(directoryTxt.value,'r')
            t=f.read()
            f.close()
        except Exception as e:
            t='error!'
            errorTxt.value=str(e)
        print(t)
        readTxt.value=str(t)
        page.update()
        time.sleep(2)

ft.app(main)

Error message

[Errno 13] Permission denied: '/system/storage/emulated/0/test/text.txt'

this link '#2541' seems to have an answer but i don't quite understand what needs to be done.
