Hm, okay. Do Android tests not run as part of CI? Why was this green and got merged?

[mdh1418]

@vcsjones They are on CI, but they're non-blocking and show up in runtime-staging because of flakey reasons such as infrastructure failures, hitting a bad machine on the osx hosted pools, etc. As long as the build/lane completes its marked green on the github UI, but on close inspection by clicking the runtime-staging lane https://github.com/dotnet/runtime/pull/59674/checks?check_run_id=3740236485 the error is shown but again non-blocking.
