I’m trying to add a library reference to a project and when I go to the Project > Properties > Android window and click Add, the library project is grayed out (see below). Any idea why this is happening?
The Android sdk is being referenced in the preferences and a build target (version 7) is selected.
Thanks

Add/import the project you want to reference as a library into Eclipse and make sure you have it open. The library’s API level may not be higher than your project.
If the project is already selected as a reference, you will have to remove it first.
I’m not sure if the JDK version is relevant, but I recall having problems with referenced libraries under version 1.6.
