I'm trying to build Skia for Android and followed the documentation here.
Eventually I ended up using this configuration:
bin/gn gen out/arm64 --args='ndk="../Android/sdk/ndk-bundle" target_cpu="arm64" is_component_build=true is_official_build=false skia_enable_svg=true'
The building process with ninja -C out/arm64 finished without any errors, then I've included the generated libskia.so in an Android project.
The Android project cannot be built if I reference Skia methods SVG related (SkSVGSVG and SkSVGDOM).
The issue is related to an error when I try to use actual SVG APIs. Other Skia APIs seem to work fine. In particular, the error message is this:
ld: error: undefined symbol: SkSVGSVG::intrinsicSize(SkSVGLengthContext const&) const

clang++: error: linker command failed with exit code 1 (use -v to see invocation)

It seems that the SVG module is missing completely, is there a way to verify this? Is it even possible to achieve a Skia build for Android with SVG support? I spotted this old thread of messages in the Chromium bug tracker and it seems libsvg.so does not export symbols. (Do I have to include libsvg.so in my Android project?)
