title: Android Play-store behavior on app download
body: <p>I was just curious to know few basic behavior of the google play-store.
  Tried to find the answers of below questions:</p>
  
  <p>1) If my phone network is switched from cellular to WI-FI while i am downloading an app from the play- 
     store. How google manages the connection as it resumes the download from where it stopped, because as 
     far as i know the IP address will change and TCP connection restarts the session.</p>
  
  <p>2) What are the detailed steps involved right from requesting for an app from play-store till it is 
     installed in our device. I mean what are the factors of the device google crosschecks, for instance,<br>
     if the minimum version of the app is 7.0 and i have a device of 6.0, will the .apk gets downloaded and 
     then the version is verified or it is verified before the download starts.</p>
  
  <p>Couldn't able to find a document on these. Please share if you have one.</p>
