Agent Quick Fix

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

Product: Firebase Android
Current-contract area: Firebase Messaging raises minSdk to 23
Likely root cause: FCM dependency upgrade forces the app's minimum Android API higher.
Repair direction: Verifier checks an explicit product decision: raise the app floor with metadata/tests, or pin a still-supported SDK line. Check the resolved dependency graph and runtime behavior on the declared minimum platform.

Symptom

FCM dependency upgrade forces the app's minimum Android API higher.

Why This Happens

The source can compile on the developer's newer device while the SDK's newly raised deployment/minSdk target fails older build or runtime matrices.

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.
