Oct 1, 2025October 2025 performance summary for google/oboe: Delivered Safe AAudio stream lifecycle management to increase stability and reduce crash risk in the AAudio path. Introduced AAudioStreamCollection singleton to track stream lifetimes and provide safe shared access, ensuring callbacks are only processed while streams are alive. Hardened error handling by validating liveness before accessing stream members in error callbacks. These measures reduce crash surface, improve reliability across Android audio routes, and establish a safer foundation for future streaming features, contributing to better user experience and lower maintenance costs.
