Be aware that we don't generally attempt to support all devices, only those that run in continuous integration specifically (in this case, the Android 7.0 x86_64 emulator), or rooted devices in general.

What https://bugzilla.mozilla.org/show_bug.cgi?id=1584933#c1 is true, but junit tests really shouldn't require root. If they do, it's quite likely our harness that requires root and not the test itself, which means we're likely to break Android Studio workflows -- and those are critical to the velocity of the team.

Now, Andreas: that log doesn't include anything about failing tests. Can you produce a complete log file and adb logcat output?

So it turns out that this was somewhat of a red herring. Trouble was that ./mach bootstrap could leave you in a strange state if you failed accepting licenses. After clearing toolchains and bootstrapping again, the problem went away.
