PR Analysis

Problem: IterableApi.getInstance().getPayloadData() retains notification payload data indefinitely after a push notification is opened. There is no public API to reset it, so consumers cannot distinguish between "a notification was just opened" and "stale data from a previous notification" once they have finished processing it.

Ideal fix plan:

• Add a public method to clear _payloadData (set it to null) so consumers can reset it after processing
• Alternatively, the SDK could auto-clear payload data after it has been consumed (e.g., after the first getPayloadData() call or after onResume completes), but that would be a breaking behavioral change, so a manual clear method is the safer, non-breaking approach
• Add a unit test that sets payload data, calls the new clear method, and asserts getPayloadData() returns null

What the PR did:

• Added a public clearPayloadData() method that sets _payloadData = null
• Added Javadoc explaining when to call it
• No tests included (only a manual test plan in the PR description)

Assessment:

• Root cause identified: yes -- the field is set on notification open and never cleared, with no public API to reset it
• Fix correctness: correct -- a public nulling method is the minimal, non-breaking solution; naming (clearPayloadData) is consistent with common Android SDK conventions
• Missed: unit tests -- a simple test (set bundle via the package-private setPayloadData, call clearPayloadData, assert getPayloadData() is null) should be straightforward and would prevent regressions. The PR lists manual test steps but does not add automated tests.
• Wrong assessment: none
• Tests: needed but missing
