Android Java: Fastest Method for Pixel Color Retrieval

In Android Java, you can retrieve the color of a pixel using the Bitmap.getPixel() method. This method takes two parameters: the x-coordinate and y-coordinate of the pixel. It returns an int value representing the pixel's ARGB value, where 'A' stands for alpha (transparency), 'R' for red, 'G' for green, and 'B' for blue.

For example, the following code snippet retrieves the color of the pixel at coordinates (10, 10) within a bitmap:

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.image);
int color = bitmap.getPixel(10, 10);
int red = Color.red(color);
int green = Color.green(color);
int blue = Color.blue(color);

The Color.red(), Color.green(), and Color.blue() methods extract the R, G, and B components from the ARGB value respectively.
