"arm64-v8a", "x86" and "x86_64" are all errors except "armeabi-v7a" when I compile webrtc-android m98 with the command line(The 'use custom libcxx=false' parameter is mandatory). Please help to see what the solution is! thanks!
cmd:
python3 tools_webrtc/android/build_aar.py --extra-gn-args 'is_debug=false is_component_build=false is_clang=true rtc_include_tests=false rtc_use_h264=true rtc_enable_protobuf=false use_rtti=true use_custom_libcxx=false' --build-dir ../out/release-build/
