title: Android Test cases not working in debug mode
body: <p>I am not able to debug android Instrumentation test cases (using espresso &amp; UiAutomator) </p>
  
  <p>But earlier test cases the debugging was working fine but with recent update it is not working anymore. It gets always struck up at instantiating unit test

  <p>I can see in command window that it's trying to launch PACKAGE_NAME**.test** </p>
  
  <pre><code> adb shell am instrument -w -r   -e debug true -e class PACKAGE_NAME.LanguageScreenTest#testSelectImportant PACKAGE_NAME**.test**/android.support.test.runner.AndroidJUnitRunner
  </code></pre>
