    "actions": {
        "SomeAction": {
            "conditions": [],

我在Camera2上使用此功能作为火炬

@TargetApi(Build.VERSION_CODES.M)
public void toggleMarshmallowFlashlight(boolean enable) {
    try {
        final CameraManager manager = (CameraManager) mContext.getSystemService(Context.CAMERA_SERVICE);
        final String[] list = manager.getCameraIdList();
        manager.setTorchMode(list[0], enable);
    } catch (CameraAccessException e) {
    }
}
