IllegalArgumentException：容量错误

Question

在实现将图像转换为灰度的方法后，我收到了这个奇怪的错误：

public Bitmap toGrayscale(Bitmap bmpOriginal)
{
    int width, height;
    height = bmpOriginal.getHeight();
    width = bmpOriginal.getWidth();
    Bitmap bmpGrayscale = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
    Canvas c = new Canvas(bmpGrayscale);
    Paint paint = new Paint();
    ColorMatrix cm = new ColorMatrix();
    cm.setSaturation(0);
    ColorMatrixColorFilter f = new ColorMatrixColorFilter(cm);
    paint.setColorFilter(f);
    c.drawBitmap(bmpOriginal, 0, 0, paint);
    bmpOriginal.recycle();
    return bmpGrayscale;
}

错误：

应用程序在没有 toGrayscale 方法的情况下正常工作。但我真的需要它。试图添加recycle（）;代码中到处都是方法，以防止超出内存，但它无法正常工作。我无法回收 bmpGrayscale ，因为我需要返回。知道什么可能是错的吗？
