I ran into this problem as well, but I was (apparently) able to get everything working fine with a workaround. Since it doesn't look like you posted a logcat, I'll assume you ran into the same issue I did.
Yes, you do need to list beautifulsoup4 as a requirement in your spec. From looking into bs4's code, it looks like bs4 is willing to use any of several "builders." It supports HTMLParser, html5lib, or lxml. I have no idea why we can't load HTMLParser, but it's actually the least preferred library of the three, and if it weren't for the fact that there's no try block around the import, it seems that everything would work fine (as long as one of the other parsing libraries was available).
With this in mind, I included one of the other libraries, and I decided to hack the import process so that Python would pretend _htmlparser loaded okay :)
This article was instructive: http://xion.org.pl/2012/05/06/hacking-python-imports/
The end result was something like this:
import imp
import sys
class ImportBlocker(object):
def __init__(self, *args):
self.black_list = args
def find_module(self, name, path=None):
if name in self.black_list:
return self
return None
def load_module(self, name):
module = imp.new_module(name)
module.__all__ = [] # Necessary because of how bs4 inspects the module
return module
sys.meta_path = [ImportBlocker('bs4.builder._htmlparser')]
from bs4 import BeautifulSoup
I also added html5lib to the requirements in buildozer.spec.
Now, is this the right way to solve the problem? I don't know. The best approach would probably be to request that the author fix it. It might be as simple as to put the import in a try block. Nevertheless, this is the approach I've gone with for the moment, and it is at least an interesting exercise, and a way to test your app until a better fix comes along.
Additionally, I should warn you that I only did this recently, so I can't 100% guarantee that it won't cause any problems, but at a minimum, it's worked well enough to get my app running and scraping the particular website I was interested in. Good luck!
