The Africa Android Challenge is an opportunity to discover the best developers and Android experts on the African continent.  The contestants have an opportunity to create innovative applications and produce local "African" content.  In addition, they can submit lectures related to Android on the Android Platform via the Google University Consortium Program.

This whole effort is community driven and is a way to assure the long-term success of African developers invested in the Android application environment.  We also expect that such initiative will lead to the discovery of unexpected, rich, and valuable local content and applications.
