Mastering C++ NDK for Low-Latency Edge AI on Android
Edge AI on Android requires bypassing the JVM's abstraction tax via C++ NDK for performance. Direct ByteBuffers enable zero-copy data transfer, while coarse-grained JNI calls minimize overhead. This approach is critical for running LLMs like Gemini Nano on-device with low latency.

The piece correctly identifies JNI overhead as a bottleneck, but the real-world impact depends on model size and hardware; many developers may find existing frameworks like NNAPI sufficient.
