The libcore related projects (see below) have been (mostly) switched
over to use UnsupportedAppUsage annotations, This change will prevent
entries for those projects being added to a config/hiddenapi-* file.
* libcore
* external/bouncycastle
* external/conscrypt
* external/icu
* external/okhttp
* external/libphonenumber - still has a couple of entries in
config/hiddenapi-light-greylist.txt due to limitations in
UnsupportedAppUsage/class2greylist.
Tested by attempting to upload the file with entries for libcore
projects and without those entries and checking that the behavior
is expected.
Test: see above
