  i have error message on sync.</p>
  
  <p><img src="https://i.stack.imgur.com/MCBqk.png" alt="Error alert"></p>
  
  <p>If I click the UPDATE button it changes the version in the gradle build file but then an other error.</p>
  
  <p><img src="https://i.stack.imgur.com/HVzh4.png" alt="5.6.4 error"></p>
  
  <p>version 5.6.4 doesn't exist.</p>
  
  <p>the highest version is 2.3.1</p>
  
  <p><a href="https://jcenter.bintray.com/com/android/tools/build/gradle/2.3.1/" rel="nofollow noreferrer">https://jcenter.bintray.com/com/android/tools/build/gradle/2.3.1/</a></p>
  
  <p>This seems an unsolvable problem.</p>
