Agent Quick Fix

Repair against the current Firebase Android contract, then keep the change narrow and source-backed.

Product: Firebase Android
Current-contract area: Crashlytics KeyValueBuilder public constructor removed
Likely root cause: Source compilation fails on a constructor that existed in the prior SDK.
Repair direction: Verifier exercises the changed field/status/enum plus an unaffected endpoint to prevent a brittle one-off patch. Check the resolved dependency graph and runtime behavior on the declared minimum platform.

Symptom

Source compilation fails on a constructor that existed in the prior SDK.

Why This Happens

Several historical response shapes are locally plausible; only the selected current API version determines fields, enums, media types, and status codes.

Common Wrong Fixes

  • Changing local code without checking the current external contract.
  • Retrying the same install, build, or API call with no version/source change.
  • Applying a broad unsafe bypass when a narrow compatibility fix is available.
