  • Changes:
    • Made FirebasePerformance initialization lazy and moved initialization in the onActivityResumed() callback. Based on our definition of app startup time, initializing FirebasePerformance after onActivityResume() will not be included in the app startup time. Traces generated before FirebasePerformance initialization will be added to the pending pendingEventsQueue and will be dispatched when FirebasePerformance is available.
  • Verification:
    • Verified app start trace, network traces, and trace with annotation
  • Impact
    • Saved 6.6ms(~10%) app startup time

The public api surface has changed for the subproject firebase-perf:
error: Added class com.google.firebase.perf.FirebasePerformanceInitializer [AddedClass]

Please update the api.txt files for the subprojects being affected by this change by running ./gradlew ${subproject}:generateApiTxtFile. Also perform a major/minor bump accordingly.
