API changes
- Channel mask support is supported for AAudio in API 32 and above (#1548)
- Add methods
setDelayBeforeCloseMillisandgetDelayBeforeCloseMillisto audio streams (#1593) - Add OboeExtensions (#1602). These will allow you to query for, enable, and disable MMAP support.
- Add shared_ptr support for
setDataCallbackandsetErrorCallback(#1626). The equivalent for raw pointers is now deprecated. This helps avoid crashes by preventing the callback from being deleted while the error callback is still active.
