title: AndroidStudio: JaCoCo code coverage report's 0% for coverage
body: <p>I've recently brought code coverage into my project.  It creates a report, which I can view, and it seems to be working great.</p>
  
  <p>The only problem is it is missing my tests - I don't have GREAT code coverage right now, but it reports 0% coverage for all classes and other files.</p>
  
  <p>I can see the tests being run, and can see them passing, but they aren't being counted.</p>
  
  <p>My configuration is:</p>
  
  <pre><code>android {
      compileSdkVersion 18
      buildToolsVersion '21.1.1'
      ...
       debug {
              minifyEnabled false
              testCoverageEnabled = true
          }
  }
  </code></pre>
