Solution 1:

The jar file you are linking to needs to be in the libs folder and/or marked for export. You can mark for export in Eclipse by right-clicking your project and selecting Properties>Java Build Path>Order and Export then selecting the checkbox of the jar you have imported.

Solution 2:

The jar or library file while you add to a project, need to be in the same workspace.
