Say your bitmap is:

Bitmap bitmap;

Provided it's initialized and holds data, you can get the first pixel with:

int color = bitmap.getPixel(0, 0);

The pixels in android Bitmaps are stored as an array.

All you have to do is:

Bitmap.getPixel(x, y);

That method will return the pixel stored in the position x, y, and the bitmap range is:

0 - with on X

and 0 - height on Y.

So you have to do a sweep through all the table to get each pixel as follows:

for(int i = 0; i < bmp.getHeight(); i++){
   for(int j = 0; j < bmp.getWidth(); j++){
         int pixel = bmp.getPixel(j, i);
   }
}

Hope this Helps.

Regards!
