Genymotion is a fast and efficient Android emulator that replaces the standard Android emulator, providing a better development experience for serious developers. Genymotion achieves its speed by running an x86 version of Android in Virtualbox, which has implications for networking modes, including host-only devices that allow connecting to the host machine through a virtual interface named "vboxnet0". To use Google Play Services with Genymotion, one can install an OpenGApps bundle containing both ARM and x86 versions of GP. The installation process is relatively easy, involving downloading a zip package from http://opengapps.org/ and dragging it to the virtual device in Genymotion. With this setup, developers can take advantage of the Couchbase Mobile Training for NoSQL mobile development.
