 | `arch` | Optional | `x86` | CPU architecture of the system image - `x86`, `x86_64` or `arm64-v8a`. Note that `x86_64` image is only available for API 21+. `arm64-v8a` images require Android 4.2+ and are limited to fewer API levels (e.g. 30). |
 | `profile` | Optional | N/A | Hardware profile used for creating the AVD - e.g. `Nexus 6`. For a list of all profiles available, run `avdmanager list` and refer to the results under "Available Android Virtual Devices". |
 | `cores` | Optional | 2 | Number of cores to use for the emulator (`hw.cpu.ncore` in config.ini). |
