Do we know anything about the situations where apiVersion is showing up as null?
Is something going wrong when the tool tries to run adb getprop, or is the ro.build.version.sdk property actually missing?

It's most likely that this property is just missing. If adb getprop had failed more severely, then the tool would not have gotten this far. In particular, it wouldn't have been able to figure out the device.targetPlatform:
which boils down to a getprop call on Android:

Description
getpropcan come back without an API version. In that case the getter will be null. Previously this was used only for filling out aString, but recently a change also used it to decide what flags to pass tologcat. This change makes the flag logic handle the null case.Related Issues
Most frequent tool crasher on dev.
Tests
I added the following tests:
Added tests to android_device_test.dart.
