Need to follow Test your Changes to test the changes made by #1 (64bit support)

[UPDATE] Just ran e2e tests as noted here. It was a manual test. The scripts builds the lib and facilitate installing both Android and iOS versions for testing.

Results: both apps ran fine. Android had an issue downloading the size of an image (will look into it next). Also, will try to run ci tests.

[UPDATE] Submitted a PR to facebook to be able to run all ci tests

All tests are passing on the facebook PR facebook#19536.
