title: Android Studio 2.3 update : Warning:Using incompatible plugins for the annotation processing: android-apt. This may result in an unexpected behavior
body: <p>So, I have read all the questions I could find on this site regarding this issue. I have also had a chat in comments with one of the developer with similar issue, who was able to solve it.</p>
  
  <p>I dont have apt or annotationProcessor written any where in my gradle scripts.</p>
  
  <p>I dont have the word android-apt written anywhere in my code. I even went ahead and checked out all the libraries. That were included in my project.</p>
  
  <p>This is a really big problem and needs to be solved.</p>
  
  <p>I am attaching the modified build.gradle below, Please suggest :</p>
