My main issues is that the line drawing is usually faster than images on real phones for up to 12 or so lines, but not the emulator. The drawing images and 3d is actually not that bad for fast phones of 2003, but it should be about 8 times faster. 25fps is actually really fast, but like you said it is just a single test image.
As far as speeding things up the most important thing is to reuse the Bitmap object and not create one each frame. I assume you are already doing that given your getting 25fps. Not much other than that is going to dramatically increase performance. If you follow Google performance advice document you are doing just about everything you can do. Remember the first arcade games that sold millions of copies only got 5-7 fps.
