title: Android Espresso Tests for phone and tablet
body: <p>My setup:
  - Android App with Phone and Tablet Version
  - I am using Android Espresso for UI-Tests (now only for phone version, with phone at buildagent)</p>
  
  <p>What I want to do:
  - Now I want Espresso to distinguish between tests for phone and tablet
  - So Test A should be only execute by a tablet, Test B should only be executed by a phone and Test C both
  - Tests should be executable via gradle task</p>
