I use the UniFFI Kotlin bindings, and when I analyze my APK, I can see that libmdk_uniffi.so file uses 6.3MB (plus another 5.2MB for armv7. This is the largest library in my app). Other libraries like rust-nostr use configuration code like this to optimize space:
[profile.release]
opt-level = 'z' # Optimize for size
lto = true # Enable Link Time Optimization
codegen-units = 1 # Reduce the number of codegen units to increase optimizations
panic = "abort" # Abort on panic
strip = true # Full strip the binary. A debug binary will be used for generating UniFFI foreign languages!

I don't know how much something like this would help, but the smaller the better!
