Note: The Neural Networks API is available in Android 8.1 and higher system images. The header file is available in the latest version of the NDK. We encourage you to send us your feedback via the Android 8.1 Preview issue tracker.

The Android Neural Networks API (NNAPI) is an Android C API designed for running computationally intensive operations for machine learning on mobile devices. NNAPI is designed to provide a base layer of functionality for higher-level machine learning frameworks (such as TensorFlow Lite, Caffe2, or others) that build and train neural networks. The API is available on all devices running Android 8.1 (API level 27) or higher.

NNAPI supports inferencing by applying data from Android devices to previously trained, developer-defined models. Examples of inferencing include classifying images, predicting user behavior, and selecting appropriate responses to a search query.

On-device inferencing has many benefits:

Latency: You don’t need to send a request over a network connection and wait for a response. This can be critical for video applications that process successive frames coming from a camera.

Availability: The application runs even when outside of network coverage.

Speed: New hardware specific to neural networks processing provide significantly faster computation than with general-use CPU alone.

Privacy: The data does not leave the device.

Cost: No server farm is needed when all the computations are performed on the device.

There are also trade-offs that a developer should keep in mind:
