title: Android plugin 1.3 error
body: <p>This is error I got when updated my SDK and Build tool to <strong>Android M</strong></p>
  
  <pre><code>Android Build Tools
  Found incompatible Build Tools and Android plugin versions:
  * Module 'app' is using Android plugin 1.2.3 and Build Tools 23.0.0 rc1
  Please use Android plugin 1.3 or newer, or an older Build Tools version.
  Otherwise the project won't build.
