Make sure to do the following (from Support Library Setup):
Right-click the library project folder and select Build Path >
Configure Build Path.In the Order and Export tab, check the .jar files you just added to
the build path, so they are available to projects that depend on this
library project. For example, the appcompat project requires you to
export both the android-support-v4.jar and
android-support-v7-appcompat.jar files.Uncheck Android Dependencies.
