title: Testing android with FitNesse error: "Could not invoke constructor for .." & "The instance ... does not exist"
body: <p>I am trying to figure out how FitNesse works and didn't succeed to run successfully a test.
  Does anyone can help me what I am missing?</p>
  
  <p>I have followed all steps from the book "Android Application Testing Guide" .
  I have an android sample project TemperatureConverter and a test project TemperatureConverterTest.</p>
  
  <p>Bellow is my FitNesse Wiki:</p>

  !define TEST_SYSTEM {slim}
