    // according to the values in the array.
    for(int i=0;i<WIDTH;i++){
        for(int j=0;j<HEIGHT;j++){
            // If the point is in the Set, color it White, else, color it Black.
            if(values[i][j]) image.setRGB(i, j, Color.YELLOW.getRGB());
            if(!values[i][j]) image.setRGB(i, j, Color.PINK.getRGB());
        }
    }

I didn't test but this may help:

Bitmap image = Bitmap.createBitmap(WIDTH, HEIGHT, Config.ARGB_8888);
for(int i=0;i<WIDTH;i++){
        for(int j=0;j<HEIGHT;j++){
            if(values[i][j]) image.setPixel(i, j, Color.argb(a, r, g, b));
            if(!values[i][j]) image.setPixel(i, j, Color.argb(a, r, g, b));
        }
}
