Summary:
This diff updates the minimum gradle plugin version for building the
Hermes OSS release in order to avoid problems in older versions of
the Android NDK.
Specifically, there was a bug
(android/ndk#1166) in the Android NDK that
caused the exception handling functions in
libc++
to be incorrectlyexported. Depending on link order, this can lead to
libhermes.so
not statically linking in
_Unwind_resume
, and expecting it insteadto be resolved dynamically to the version in
libc++
. However, ifwe're linking against an RN version that was built against the new
version of the NDK, those symbols may not be exported, and end up
unresolved (which crashes the app).
To allow Hermes to be built with newer versions of the NDK, we need
to bump up the gradle plugin version to 4.1. RN already uses 4.1.
