# NNAPI Execution Provider [Android Neural Networks API (NNAPI)](https://developer.android.com/ndk/guides/neuralnetworks) is a unified interface to CPU, GPU, and NN accelerators on Android. ## Minimum requirements The NNAPI EP requires Android devices with Android 8.1 or higher, it is recommended to use Android devices with Android 9 or higher to achieve optimal performance. ## Build NNAPI EP For build instructions, please see the [BUILD page](../../BUILD.md#Android-NNAPI-Execution-Provider). ## Using NNAPI EP in C/C++ ``` Ort::Env env = Ort::Env{ORT_LOGGING_LEVEL_ERROR, "Default"}; Ort::SessionOptions sf; Ort::ThrowOnError(OrtSessionOptionsAppendExecutionProvider_Nnapi(sf)); Ort::Session session(env, model_path, sf); ``` The C API details are [here](../C_API.md#c-api).
