This technology should enable more developers to test with the Android Emulator. That said, we still recommend that developers publish both x86 and ARM ABI variants of their apps to achieve the best physical device performance and reach as many users as possible. Going forward, we plan to roll this technology out across a wider variety of API levels and ensure that it supports testing all use cases that a physical device would. Given that this is a new technology, please let us know of any problems via our Issue Tracker.
