Modify DocumentLoader correspondingly. Take Android bug 32588 into account. Ideal would be to extend the XDevice stuff, or something, so that one could hand it a pre-allocated RGBA buffer into which the drawing/rendering would go. Then one could get rid of the silly convert-to-BMP phase, which prefixes the bitmap data with BMP and DIB headers (and thus, I guess, has to copy and allocate another copy). Will see.
