        if platform == 'android':
            from android.permissions import Permission , request_permissions
            def callback(permissions,results):
                if all([res for res in results]):
                    print("Got all Permissions")
                else:
                    print("did not get all permissions!")
            request_permissions([Permission.WRITE_EXTERNAL_STORAGE,Permission.READ_EXTERNAL_STORAGE] , callback)

I finally figured it out! It was due to Android version update in 2019 . It is working on below Android 10 devices but not working on Android 10 or higher because they restricted external file storage access directly. See this answer. Solution for this problem is we can use Internal app storage for creating folder and files but when we uninstall our app we will lose all files that we stored.
