ABBYYモバイルイメージングSDK、Nullpointer @OnImageOperationSelected

ここでも、ABBYYSDKの別の問題が発生しています。

このSDKを使用して画像をロードすることができました。次に、ImageOperationを実行します。ただし、nullpointer例外が発生します。

コード：

snijden.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            /*bitmapHeight = resized.getHeight();
            bitmapWidth = resized.getWidth();

            ratioWidth = (double) imageViewWidth / (double) bitmapWidth;
            ratioHeight = (double) imageViewHeight  / (double) bitmapHeight;
            Bitmap bitmap = crop.crop(resized, ratioWidth, ratioHeight);
            imageView.setImageBitmap(bitmap);
            imageView.setScaleType(ImageView.ScaleType.FIT_CENTER);
            */
            Log.d("mainactivity", "" + operations.get(2));

            Log.d("operation controller", "" + new ControllerToGreyscale() + " something");
            onImageOperationSelected(operations.get(2));
        }
    });

private void onImageOperationSelected( final ImageOperation imageOperation ) {
    Log.d( "MainActivity", "onImageOperationSelected()" );
    if( imageOperation != _imageOperation ) {
        _needUpdateSource = true;
    }
    _imageOperation = imageOperation;
    _operationController = imageOperation.getController();
    addWidgets( _operationController );
    _operationController.setResultView( _imageView, IN_SAMPLE_SIZE );
}

private void addWidgets( final OperationController operationController ) {
    _controlsContainer.removeAllViews();
    final List<ParametrControl> controls = operationController.createControls( this );
    for( final ParametrControl control : controls ) {
        _controlsContainer.addView( control.getView() );
    }
}

ここでの問題は、ImageOperation値がないと言っていることです。ただし、サンプルアプリ（SDKに付属）は私のアプリと同じ値を渡します。しかし、私のアプリではnullpointerを提供し、サンプルアプリでは実行します。

誰かがこのnullpointer問題を解決する方法を知っていますか？

上記のコードは、このSDKを使用するために必要な無限のクラスのほんの一部です。

ImageOperationクラス。

public enum ImageOperation implements LabeledColoredItem {
AUTO_BRIGHTNESS_CONTRAST(R.string.auto_brightness_contrast, new ControllerAutoBrightnessContrast(),
        OperationType.FILTER),
AUTO_ENHANCE(R.string.auto_enhance, new ControllerAutoEnhance(), OperationType.FILTER),
CONVERT_TO_GREYSCALE(R.string.convert_to_greyscale, new ControllerToGreyscale(), OperationType.FILTER),
//CROP(R.string.crop, new ControllerCrop(), OperationType.FILTER),
RECOGNIZE_EDGES(R.string.recognize_edges, new ControllerRecognizeEdges(), OperationType.DETECT);

/** Text resource's ID representing the name of the operation */
private final int _labelResourceId;

private OperationController _controller;

private OperationType _type;

/**

 *            text resource's ID representing the name of the operation

 *            operation type: filter/detector/preset
 */
private ImageOperation( final int labelResourceId, final OperationController control,
        final OperationType type ) {
    _labelResourceId = labelResourceId;
    _controller = control;
    _type = type;
}

public OperationController getController() {
    return _controller;
}

@Override
public String getLabel( final Context context ) {
    return context.getString( _labelResourceId );
}

public OperationType getType() {
    return _type;
}

public static enum OperationType {
    FILTER,
    DETECT,
    PRESET;
}

@Override

            return context.getResources().getColor( R.color.presetColor );
        default:
            return -1;
    }
}

/**

 * Filter operations comes first, then detectors, then presets. Inside the group - by alphabetical order.
 */
public static class ImageOperationComparator implements Comparator<ImageOperation> {
    private final Context _context;

    public ImageOperationComparator( final Context context ) {

    }

    @Override
    public int compare( final ImageOperation first, final ImageOperation second ) {
        if( first._type.ordinal() < second._type.ordinal() ) {
            return -1;
        }
        if( first._type.ordinal() > second._type.ordinal() ) {
            return 1;
        }
        return first.getLabel( _context ).compareTo( second.getLabel( _context ) );
    }
}
