title: Test launch failed due to internal error: Running tests on UI thread
body: <p>I am creating a unit testing project for my application. It was working fine before. but I had updated the <strong>ADT plugin</strong> and <strong>android SDK</strong>. after that I could launch this project but cannot separately run the <strong>test cases</strong>. It will execute first test case and then stop. Before I could manually execute the second testcase.  But now when I tried to do that I got error "Test launch failed due to internal error: Running tests on UI thread".please help me to solve this...<br>
  note:using robotium 3.2.1</p>
