mockingbird_android #

The Android implementation of the mockingbird plugin. It is endorsed, so depending on mockingbird includes it automatically.

What it bundles #

The Mockingbird engine compiled from source by the plugin's CMake build: capture, RNNoise, libfvad, the anomaly gate, the Opus encoder, and the ONNX Runtime detectors (Silero VAD and YAMNet) through the onnxruntime-android AAR.
Microphone capture through Oboe, with miniaudio as the fallback backend.
16 KB page alignment for the shared library, as Android 15 requires.

The Dart side opens libmockingbird.so with DynamicLibrary.open and talks to it over dart:ffi. There are no platform channels.

Setting	Value
minSdk	21
compileSdk	37
NDK	r28 or newer; the plugin pins r30
Android Gradle plugin	9.1 or newer, with or without built-in Kotlin
ABIs	arm64-v8a, x86_64

Add the microphone permission to your app's manifest and request it at runtime before starting an engine that captures:

<uses-permission android:name="android.permission.RECORD_AUDIO" />

Engines created with MockingbirdBackend.hostPcm do not touch the microphone and need no permission.
