I've seen something like this before when developing locally every once in a while. That an app cannot be updated because the previous version of the app is incompatible (usually signed different). But that was on iOS if I'm not mistaken.
Maybe Android has introduced a similar feature?

@reidbaker Who knows how the Android devices in the device lab work?
I would expect the device to not already have an app installed.
If the devices do not have apps removed, we should investigate if we can adb "uninstall" the app first in the test.

edit: It already does uninstalling

The two failures in the last 100 runs have different causes:

[2024-05-12 02:44:36.560587] [STDOUT] stdout: [        ] Waiting for VM Service port to be available...
(and then just hangs)

Step failed (timeout) (retcode: -15)

and

Both of these issues seem unrelated to the specific test.
