[REQUIRED] Step 2: Describe your environment

• Android Studio version: Android Studio Narwhal Feature Drop | 2025.1.2 Patch 1
• Firebase Component: firebase-perf
• Component version: 22.0.2

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

1. Clone and run firebase-android-sdk
2. Add com.google.firebase.perf.v1.TraceMetric.newBuilder() to com.google.firebase.quickstart.perfmon.kotlin.MainActivity
3. Run "perf.app"
4. Actual result: Cannot access 'GeneratedMessageLite' which is a supertype of 'TraceMetric'. Check your module classpath for missing or conflicting dependencies.

I can fix it add implementation("com.google.protobuf:protobuf-javalite:3.25.5")

Relevant Code:

import com.google.firebase.perf.v1.TraceMetric

TraceMetric.newBuilder()

Error occurred since com.google.firebase:firebase-perf:21.0.5

Hi @AntonMishanin , thank you for reaching out. I was able to reproduce the behavior you raised. However, the TraceMetric.newBuilder() is an internal and system-generated class through protobufs. This method is not intended for direct use. Firebase Performance SDK uses protobuf-javalite:3.25.5

firebase-android-sdk/gradle/libs.versions.toml

Line 43 in de40e0a

javalite = "3.25.5"

firebase-android-sdk/firebase-perf/firebase-perf.gradle

Line 107 in de40e0a

implementation libs.protobuf.java.lite

If you want to add custom monitoring, the standard approach is by using Trace class from the com.google.firebase.perf.metrics package. Please see this documentation for more information.

Could you share why are you using the TraceMetric.newBuilder() directly?
