From yesterday, we kept encountering failure with error: "virtual-device-testing-for-android@1.0.1 (exit code: 1) ". We have clarified that there’s no failure caused by our UI test. Can someone help to check if the virtual device configuration is correct? Thanks in advance.

Hi @Conjuror,

Can you please:

1. Try to rebuild the build and let us know whether that helps?
2. If it would not, then please copy paste the related build’s [bitrise.io](http://bitrise.io) URL so that we can look into it!
