May 1, 2025May 2025 monthly summary for firebase/firebase-android-sdk focusing on telemetry, API modernization, and stability improvements. Delivered telemetry and analytics header enhancements to improve feature adoption tracking and backend differentiation, and completed a Voice API overhaul to modernize the API surface and prepare for future migrations. Implemented Android bidi usage tracking via initial WebSocket headers with extracted header-application logic; added Kotlin SDK usage suffix in headers to differentiate Vertex AI/developer usage; updated user-agent strings in GenerativeModel variants to include -ai for AI-related models. Replaced deprecated Voices enum with a new Voice class, updated SpeechConfig accordingly, and published CHANGELOG guidance. Resolved header placement issues to ensure telemetry accuracy and updated release notes for developer guidance. These changes increase telemetry fidelity, API stability, and ease of migration for customers.
