title: Android - How to intercept the 'Install application' intent
body: <p>OK, so not entirely sure this is possible...</p>
  
  <p>But trying to write an application so that I can run some code before any of the following activities are performed.</p>
  
  <p>1) APK is downloaded from web and market launches installer</p>
  
  <p>2) Install button is pressed on android market</p>
  
  <p>Is it possible to intercept and prompt on these events, or has Google locked that stuff down quite tightly?</p>
