Since that using Robotium Library as 'Android Private Library" could not add JavaDoc, following we would illustrate the way on how to add Robotium JavaDoc to the Robotium Library, assuming which's been added to the test project as an External 
Step 1: Choose "Robotium-solo-xxx.jar>Javadoc locationL(None)" and then click on the Edit button as following screenshot shows.
