Thanks, I don't know all the ins and outs of Google support levels.
Though it seems that starting in April, that library environment is now
supporting only API levels 21 and up
<https://developer.android.com/jetpack/androidx/versions>, which
corresponds to Android 5.0 and later.
So, as I understand it, even though Google supports only Android 12 (API
31, 2021) and later, in the sense that it no longer issues security
patches etc. for older Android releases, Google also supplies extensions
to Android (called Jetpack) that are separate and that will run on
Android releases back to Android 5.0 (API 21, 2014).
Given that the strnlen bug was fixed in Android 5.1 (API 22, 2015), the
only remaining problematic Android release is Android 5.0, where the
Gnulib strnlen module doesn't detect the Android bug and therefore
doesn't work around it. Presumably Google will update Jetpack's minimum
supported API soon, at which point this issue will become academic. The
abovementioned URL says that about 99.2% of Android users are running
5.1 or later and so shouldn't see the problem. Since only about 0.3% of
Android users are running 5.0 perhaps it's not worth worrying about this
for Gnulib.
