I installed TADP but eclipse from TADP have no Android tool

I installed Tegra Android Development Pack 2.0r7 by seleceted Express. I want to run openCV sample from TADP. But when I open Eclipse KEPLER from TADP it have no android tool . The sample openCV Package show error The project was not built since its build path is incomplete. I right click at Package and click Properties it have no android for set Project Build Target. I click cancel and look at tool bar it also have no android tool . How to use TADP compile openCV sample ?

could you check you Eclipse SDK path and clean/build again?
