Test launch failed due to internal error: Running tests on UI thread
===

I am creating a unit testing project for my application. It was working fine before. but I had updated the **ADT plugin** and **android SDK**. after that I could launch this project but cannot separately run the **test cases**. 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...  
note:using robotium 3.2.1
