title: Buildozer, How to add external python packages?
body: <p>I have built a kivy app using Python 2.7. I have used the import statements</p>
  
  <pre><code>from kivy.app import App
  from kivy.uix.floatlayout import FloatLayout
  from kivy.uix.widget import Widget
  from kivy.properties import *
  from kivy.uix.textinput import TextInput
  from kivy.uix.image import Image
  from kivy.uix.image import AsyncImage
  from kivy.uix.button import Button
  from kivy.uix.label import Label
  from kivy import Config
  import sqlite3
  import webbrowser
  from kivy.lang import Builder
  import re
  from bs4 import BeautifulSoup
  import unicodedata
  from threading import Thread
  import requests`
  </code></pre>
  
  <p>In my Buildozer.spec file</p>
  
  <pre><code>requirements = kivy,requests,bs4
  </code></pre>
  
  <p>I have set the requirements to use these, as the rest of the packages are inbuilt in Python. I did not specify them. The APK Gets built and I run it on my android phone and the app crashes without any error. I dont understand where the problem lies. If it is my buildozer spec requirements or improper usage of packages.</p>
  
  <p>I have been searching all over the internet , and I have read the Buildozer docs, But I haven't been able to find a good tutorial on how to use Buildozer . I am using it on Linux. Can someone explain what is going wrong?</p>
