Can't find android.support support package

I made a folder called libs to my working space.

I copied the android开发者_开发问答-support-v4.jar in it.

Pressed right on it Build Path > Add to Build Path.

Next i added a library and there it needs the Viewpager.

Afterwards i cleaned my project, but i cann't access android.support.v4.view.ViewPager.

Eclipse don't find android.support as well

Solutions?

You should add the library to your build path after you copy the file in the libs directory.

Once you copy the file in libs directory, right click on project, build path, libraries and select the libs directory of the project and add it.

You can then import the classes.
