title: Difference between elevation and translationZ
body: <p>I tried both features and I don't know really why I should use elevation instead of translationz or viceversa. </p>
  
  <p>Both generate shadow when I used them. </p>
  
  <p>I should use at same time (with the same value)? I should use just one? </p>
  
  <p>Thank you in advance!</p>
  
  <p>EDIT:</p>
  
  <p>I did a visual comparison to can see it clearly:</p>
  
  <p><img src="https://i.stack.imgur.com/ztSN9.png" alt="comparison elevation vs translationZ"></p>
  
  <p>The conclusion that I get is (at least with this range of 0 to 16 dp) one of them is dispensable.</p>
  
  <p>I see the same shadow in 8 vs 8 and 16 vs 16 and the same shadow in 16 vs 8+8.</p>
  
  <p>But I haven't a great vision, what do you think guys?</p>
