I think you will have to do that yourself.

Just create an int array with all the colors :

    Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.icon);  
    bmp = bmp.copy(Bitmap.Config.ARGB_8888, true);    
    int intArray[] = new int[bmp.getWidth()*bmp.getHeight()];  
    bmp.getPixels(intArray, 0, bmp.getWidth(), 0, 0, bmp.getWidth(), bmp.getHeight());  

Then you can get the color with intArray[0], the value could be 0xFFFF0000 for red (last 6 numbers are the RGB color value).

EDIT : Easy solution :

Get you full-size image in a bitmap.

Create a scaled bitmap of 1*1px.

Get this bitmap color.
