So you can send as many Bitmaps to the function as you need. But you can only have one varargs per parameter list, and if other args are included, the varargs must come last.

Just to further clarify, this means you can call to the method like this:

Bitmap first ;
Bitmap second ;
onProgressUpdate(first);
onProgressUpdate(first, second);

Open in new window

Java collects up the list of arguments and turns then into a Bitmap array which is then passed to the function.

It's just to save the caller from having to make the array themselves.
