Issue:

I am developing an application that is working correctly when I run directly on my computer, however I run on my phone it presents a series of errors related to BS4 (BeautifulSoup).

As one of the libraries I use is "Skpy" https://pypi.org/project/SkPy, and it makes use of BeautifulSoap, so I can not substitute it directly, since it's a third-party library.

When I comment the use of the library in the application works normally, both on the PC and on the device.

I've done tests with Python 3.6 using NDK and the current Python 2.7 model, and the error is simply the same, I do not know how to proceed.

Has anyone ever experienced this?

Sample:

# https://skpy.t.allofti.me/
from skpy import Skype

# https://pandas.pydata.org/
import pandas as pd

class SkypeBackup:

	def __init__(self, user, password, connect=False):
		
		self.user     = user
		self.password = password
		self.connect  = connect
		
		self.sk       = Skype(self.user, self.password, self.connect)

	def get_contacts_csv(self, sep=';', encoding="utf-8"):

		self.data_frame_contacts = pd.DataFrame([vars(contact) for contact in self.sk.contacts])

		return self.data_frame_contacts.to_csv(sep=sep, encoding=encoding)

#    List as sections

#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
