I've never heard anything like that. What I HAVE heard (ummm, read) is a
lot of use of ARGB_8888 and RGB_565, including my current app, for at
least part of the imagery (unprocessed image is ARGB_8888, filters
REQUIRE ARGB_8888[1], and the photo combined with the filters is RGB_565).

In fact, if you look at the docs on BitmapFactory.Options, the default
Bitmap.Config is ARGB_8888. Of course, it also says that it will try to
match the screen's color depth, and also that of the image being loaded.

So the default is Bitmap.Config for imagery is ARGB_8888 except when it
isn't. :-)

(and to think I sometimes bother to wonder how I end up so utterly
confused by these things....)

Later,
--jim

[1] I tried the filters at ARGB_4444 ... until I saw the results for
graduated filters...and ARGB_444 was OUT, and ARGB_8888 was back in.
