title: Download App from Google Play programmatically
body: <p>I need to download a few Apps from google play for analysis purpose. But I don't want to do it manually (I have to do it often and each time the Apps that I want to download change!).</p>
  
  <p>So, the question is, whether I can write a program to download the Apps or not. If it is possible, how?</p>
  
  <p>I have seen this plugin for chrome:
  <a href="http://codekiem.com/2012/02/24/apk-downloader/">http://codekiem.com/2012/02/24/apk-downloader/</a>
  but I cannot trust the author (the App requires google user and pass and device ID) and have decide to implement my own program.</p>
