title: How to disable Android emulator animations in Travis?
body: <p>I am running Espresso tests in the Travis CI. When I run my tests in my device, I normally disable all my animations so I don't have to use Thread.sleep all the time. </p>
  
  <p>But I really don't know how to do this in the Travis CI, so my tests fail without the Thread.sleep. I looked over the internet... but I didn't find any tutorial about how to do disable the animations in the emulator</p>
  
  <p>I could use idling resource in Espresso, I know. But some times I would prefer not to.</p>
