We are pleased to announce the release of Android Tracker version 4.1.1.
This release fixes a bug where the session user ID was truncated, causing events to fail validation.
When user anonymisation is configured, the session user ID (sessionContext userId) should be the null UUID 00000000-0000-0000-0000-000000000000. On certain Motorola phones, this was being truncated to the invalid 0000-0000. It’s a known bug where toString() is called on an all-zeroes UUID. The null UUID is now hardcoded, hopefully satisfying all types of phones.
CHANGELOG
Hardcode the anonymised session user ID (#566)
