title: Android Material Design - Waiting for user input
body: <p>I know we can produce very powerful animation effects in Android using AnimationUtil and xml animation files but would this be considered a good practice for Material Design, specifically for a case when we wait for user do do something.</p>
  
  <p>For example, I have activity with single image or image button on it.  User lands on this activity and is expected to tap on that image.  I want to give some feedback to user rather than having just a label like "Click here". </p>
  
  <p>I could make a nice animation using AnimationUtil class and xml file in res/anim folder.  But would that be how material design recommends it doing?  I looked through Material Design guidelines and could not find anything specific to "animation effect waiting for user input" but the screenshot below makes me believe using animation does not violate Material Design guidelines.</p>
  
  <p>Any suggestions?</p>
  
  <p>I am talking about something like this example</p>
