@vilius12G did you have a question related to that config.yml?

10

from what I see here using arm is more expensive that not using arm. will that change?

@orarbel Final pricing & specs are still being finalized, we’ll update this page & the official resource class pricing page when the functionality is “Generally Available”.

12

In the announcement post, the resource classes use the form arm.medium or arm.large. However, looking at the documentation on resource classes (Using the Docker execution environment), that table shows arm-medium, with a dash. Would you be able to clarify which form is valid?

13

@jlocsei sorry for the inconsistency, I’m working on some updates to the docs to fix that.

Both should be valid. I am going to make all of the docs use the “.” over the hyphens though.

Hi, is Android image supported?

21

@vibinr Unfortunately no as the emulator package that we rely on does not support arm64. Enable arm64 builds · Issue #88 · CircleCI-Public/cimg-android · GitHub for details

22

Are there any building benchmarks to determine if this is faster than using machine images directly?
