NNAPI Migration Guide

The Neural Networks API (NNAPI) is deprecated. It was
introduced in Android 8.1 to provide a unified interface for hardware
accelerated inference for on-device machine learning,
and deprecated in Android 15.
After NNAPI's release, the field of on-device machine learning (ODML)
advanced rapidly. Breakthroughs such as transformer and diffusion models,
along with the high rate of innovation in the field meant that
developers needed tools and infrastructure that update frequently.
To meet those needs, Google developed
TensorFlow Lite in Play Services,
providing an updatable TensorFlow runtime for custom on-device ML models,
and AICore, which provide GenAI foundation models like
Gemini Nano directly on Android devices. To provide greater clarity on
the recommended paths for production ML on Android, NNAPI (Neural Networks API)
was deprecated.
To migrate from NNAPI, see the instructions for
TensorFlow Lite in Google Play Services
and optionally TFLite GPU delegate for hardware acceleration.
