title: Code Coverage report showing 0% even after build successful
body: <p>I am generating code coverage report using jacoco and sonar in android studio. I have executed the commands successfuly by following the the video from <a href="https://www.youtube.com/watch?v=acxwRaxoGAo" rel="nofollow noreferrer">https://www.youtube.com/watch?v=acxwRaxoGAo</a>.</p>
  
  <p>I am getting build successful after execution but in sonar server it is showing code coverage 0.0%. </p>

  <p>Can anybody tell me do I need to do any other changes. I have added jacoco plugin also in my gradle file. But in sonar server the code coverage is still showing 0.0%</p>
