As some of you know, we had a problem today which caused all android tests to fail in LAVA. This is now fixed (basically, the version of adb we had installed in the lab was too old), and if you need to you should be safe to resubmit your jobs now.
Linaro insiders can see more details at https://wiki.linaro.org/Internal/LAVA/Incidents/Reports/2012-05-24-all-andro... (but really, it's not very exciting).
Apologies for the inconvenience.
Cheers, mwh
