    Install and Create Emulators using AVDMANAGER and SDKMANAGER

About


The goal of this gist is to quickly pre-install a range of system images to provide our project teams the ability to run emulators on a range of API levels, from API 19 to API 28.

These can be run locally or on the base build agent.


Note: X86 is the fastest architecture for emulators, though x86_64 would probably be better to test against because most phones are 64 bit now.
We create two sets of emulators here, one set with pixel hardware emulation and one set with default oem emulation.

See: Google Documentation on Start the emulator from the command line for more info
