Image duotone effect

I have seen that there is EffectFactory in Android and it supports Duotone effect. But it only works on API level 14 and up.

The problem is that I need the app to work from API level 11.
So my question is if there is a way to make Duotone image effect on Android below API 14?

With my current code, I access every pixel, get its RGB and change it. But I don't know how duotone works. Here is my code:

public Bitmap doColorFilter(Bitmap src)
{
    int width = src.getWidth();
    int height = src.getHeight();
    Bitmap bmOut = Bitmap.createBitmap(width, height, src.getConfig());
    int A, R, G, B;
    int pixel;

    for (int x = 0; x < width; ++x)
    {
        for (int y = 0; y < height; ++y)
        {
            pixel = src.getPixel(x, y);
            A = Color.alpha(pixel);

            R = (int) (Color.red(pixel));
            G = (int) (Color.green(pixel));
            B = (int) (Color.blue(pixel));
            bmOut.setPixel(x, y, Color.argb(A, R, G, B));
        }
    }
    return bmOut;
}

EDIT:
Sepia toning isn't working like I need it to. Here are three images:
1. original one.
2. one with modified sepia tone effect Der Golem linked
3.the one with duotone effect I need:
original
