Google released an update (Version 21) to their Android developer tooling. This update appears to have a number of issues including breaking the usage of Genymotion emulators and Android application packaging. Unless you explicitly need to upgrade, we recommend you hold off updating until Google and Genymotion provide some additional updates.
