We pre-install these system images on the base build agent to provide our project teams the ability to run emulators on a range of API levels, from API 19 to API 28. X86 is the fastest architecture for emulators, though x86_64 would probably be better to test against because most phones are 64 bit now.

1. Certain emulators, like Pixel, need to be started at a higher resolution than default oem emulators. Either define this in the ~/.android/avd/{name of avd}/config.ini file, or start emulator with -skin {RESOLUTION}.
2. Find devices with avdmanager list avdmanager list target avdmanager list devices avdmanager list avd

-   avdmanager list              : Lists existing targets or virtual devices.
-   avdmanager list avd          : Lists existing Android Virtual Devices.
-   avdmanager list target       : Lists existing targets.
-   avdmanager list device       : Lists existing devices.
