Race condition between user identity and OneTrust kit initialization on Android #605
Description
Description
We are seeing a race condition in the mParticle OneTrust kit on Android. The kit initializes before a currentUser is established. On devices with a cached previous_mpid, this is masked since a user is immediately available. However, on fresh installs or after clearing app data, currentUser is null at kit initialization. This produces the warning:
OneTrust consent could not be processed as MParticle's Current user is not set
Afterwards, when the Identity API succeeds, the kit does not retry applying consent, so consent never gets bound to the user, even if we try to update the consent by reopening the OneTrust Banner.
Steps to Reproduce:
- Fresh install the app (or clear app data, not just cache).
- Initialize mParticle with OneTrust kit enabled.
- Observe logs on startup:
OneTrust consent could not be processed as MParticle's Current user is not set
- Compare to a device with existing previous_mpid where consent attaches normally.
Expected Behavior:
The kit should either:
- Delay consent processing until a currentUser exists, or
- Listen for identity callbacks and retry consent application once a user is available
Impact
Consent state is silently dropped on first launch in fresh environments
Environment
SDK: mParticle Android SDK 5.73.2
Platform: Android Phone + Android TV
Integration: React Native app with OneTrust SDK
