title: The SDK platform-tools version ((23)) is too old to check APIs compiled with API 23
body: <p>I am getting this strange error on the first line of each file in my Android Studio. Everything was OK until I updated my Android Studio. Could someone explain to me what's going on and how to get rid of such error? I'd appreciate any help with it.</p>
  
  <p>P.S: Despite this error, I can compile and run my code successfully.</p>
