This is the complete gn args that I use to build V8 8.3.110.9 for Android: target_os = "android" target_cpu = "arm64" v8_target_cpu = "arm64" is_component_build = false is_debug = false use_custom_libcxx = false v8_monolithic = true v8_use_external_startup_data = false v8_enable_i18n_support= false symbol_level = 0 v8_android_log_stdout = true v8_enable_pointer_compression = false
I build the monolithic library then use on Android, just set "v8_monolithic" to "false" if you don't want to use the monolithic library.
