I’m building a shared object file that will be used by the JVM via JNI. Is it safe to just build it for linuxX64 and linuxArm64, and re-use the same binaries for androidNativeArm64 and androidNativeX64, or will I have to create separate binaries for linux vs. android NDK? Android is built off Linux, so I’d assume the only issue is that I won’t have access to android-specific methods.

you need separate binaries
