APIMiner is a project that aims to enrich traditional documentation with "real world" source code examples. For this purpose, we instrument the original JavaDoc by including examples extracted from real applications.

More Aqui is an Andrdoid application that aims to help people who are looking for buildings to rent or buy. Basically, the application works like an agenda, where the user registers buildings of his interest. The application then stores the building info along with its location (collected via GPS).
The application have been implemented during an Android development course, and uses the Android main features, like navigation, storing and positioning functionalities. The application source code can be found at this link.
