Neural networks API

The Neural Networks API (NNAPI) provides apps with hardware acceleration for on-device machine learning operations. The API supports on- device model creation, compilation, and execution. Apps typically do not use NNAPI directly; instead, NNAPI is meant to be called by machine learning libraries, frameworks, and tools that let developers train their models and deploy them on Android devices.
