Here's Camera/Gallery I built from 4.2 AOSP for ARMv6 (actually for ARMv5 ). Photosphere and sphereview are Google's propriatary features so the code is not published in AOSP. There's pretty much zero change of it ever working (available only for ARMv7 devices). Photo editing feature works in gallery thanks to ARMv6 compatible libs.
I've tried your camera-gallery from android 4.2. It seems that picasa sync is broken (at least for me). Also, clicking on "parameters" shows a black page. Anyway, thanks for your fantastic work, you and all the devs that made JB on blade possible !
