title: Gradle sync failed: failed to find Build Tools revision 24.0.0 rc1
body: <p>As of today I've been running into an error setting up new projects in Android Studio.  Right after creating a blank project the log mentions "Gradle sync failed: failed to find Build Tools revision 24.0.0 rc1."</p>
  
  <p>First I looked online to see how to resolve this and came across <a href="https://stackoverflow.com/questions/32111579/errorfailed-to-find-build-tools-revision-23-0-0-rc3">this similar question</a>, and followed the solution given (setting the build tools version in the module settings).  However, this results in Android Studio telling me that the method "android()" cannot be found and "The project 'TestBlankApplication' may be using a version of Gradle that does not contain the method."</p>
  
  <p>Additionally, the SDK Manager informs me that I have Build-tools 24 rc1 installed.  So I do not know why Android Studio cannot find it.</p>

  <p>Does anyone know how this can be resolved?  Thank you.</p>
