This PR fixes the compilation errors encountered during the Android build and implements several advanced performance optimizations from the Oboe main branch.
Key changes:
CMakeLists.txtto fetch Oboe frommain. This provides access to new ADPF (Android Dynamic Performance Framework) and CPU affinity APIs.reportActualWorkDurationreporting in the audio callback. This allows the Android OS to adjust CPU frequencies based on actual audio load, reducing power consumption and improving stability.StabilizedCallbackwrapper to even out callback execution times, helping the system scheduler maintain a rock-solid audio thread.AudioManagerand pass it to Oboe. This ensures AAudio uses the native hardware path, eliminating "stealth" resampling latency.oboe::Processcalls to correctly pin the audio thread to high-performance ("exclusive") cores.These changes combined should significantly reduce audio latency on modern Android devices while resolving the previous build-time failures.
