title: Automated deployment of unity3d builds to lots of android devices
body: <p>I have a lot of Android devices that all want to run the same unity app, but the refresh cycle is long to test on all of them... I have to manually update each one when a minor change is made.  Currently I'm manually downloading an apk (via http) on each device.</p>
  
  <p>Is there a way to deploy a unity app to lots of Android devices?  I have seen reference to this being possible in Android Studio, but I don't see a way to push from Unity to Android Studio for deployment, and it's not as elegant as I would like because I will need to have about 50 devices plugged in to USB.  Something over the network would be way better.</p>
  
  <p>I know this can be done with (expensive) enterprise deployment systems, but it's a little impractical when I'm making a change every few minutes.</p>
  
  <p>Is there a way to do this without Android Studio?  My build system is OSX, but any other operating system is available.  Something like a Jenkins deployment would be pretty awesome.</p>
  
  <p>Anyone have an idea?  I was thinking that the app itself could check via http for updates, and it could update itself.  It's a bit to code, but maybe is do-able.  In that case, you have to manually install the app once per device, but after that it would detect if an update is available.</p>
