ew-cli --models --json to get machine readable output with some extra information like screen sizes and densities.
Automated Test Devices
In addition to the standard models we’ve added support for the Automated Test Device (ATD for short) images. These are special emulator images that are slimmer compared to the standard ones. For example, any apps like Calendar, Dialer etc have been removed, the System UI is disabled completely and hardware rendering has been disabled to reduce load on host’s OpenGL emulation.
We’ve benchmarked these with our builds and found them to be much faster compared to non-ATD images. Read about our findings here.
If you want to know more about ATD images read the official Android Studio Preview release notes here.
