According to the Google Play Developer Program Policies (http://play.google.com/about/developer-content-policy.html), "An app downloaded from Google Play may not modify, replace or update its own APK binary code using any method other than Google Play's update mechanism."
This means that Evolve CANNOT be used in apps on Google Play.
Evolve is targeted towards apps not on Google Play and Beta tests. Some of its intended use cases are enterprise apps (fix security holes without bugging all your employees) and beta tests (push updates to beta testers instead of waiting for them to download it).
The user can use HTTPS if they want to; just put in the appropriate URL. I updated the example to reflect that.
On another note: lets keep in mind the fact that this was built within 24 hours by a motivated young student at a recent collegiate hackathon (I was there to see the presentation). It is, after all, a great hack that really shows the spirit of hacking.
..and thank you for updating the readme to be more explicit.
I enjoy testing out "fun" (sometimes buggy) features, but I hate going through the update dialog EVERY DAY.
This is ridiculous, Google Play Services does exactly that.
Why the down vote?
