The Genymotion emulator uses x86 architecture virtualization and OpenGL hardware acceleration which makes running your apps more efficient. This resulted in an emulator that was noticeably faster than the default Android emulator.ĪndroVM was bought by Genymobile and they released Genymotion which is a commercial product that improves on AndroVM. A solution to this was AndroVM which provided an Android VM client for VirtualBox. The emulator is not only slow in booting up, but on all subsequent runs of your app. Even on a powerful machine, it is manageable at best. If you have been developing Android apps for some time and have been using the default emulator, then you know how frustratingly slow it can be.
