OpenCV Engine interface cannot be resolved

edit

Dear all, I am trying to use opencv in eclipse. I have downloaded and installed Tegra Android Development Pack. When I try to import opencv using import > General > Existing Projects into Workspace > opencv folder, I get many errors. The errors are

1. OpenCVEngineInterface cannot be resolved.
2. OpenCVEngineInterface cannot be resolved to a type.
3. R cannot be resolved to a variable.
4. The container 'Android Dependencies' references non existing library 'F:\NVPACK\OpenCV-2.4.3.2-android-sdk-tadp\sdk\java\bin\opencv library - 2.4.3.jar

Can someone please help me with this. Any suggestions will be highly appreciated.

Amin.
