I tired this on ChampionSwimmers AOKP build (JB 4.1.2)....I know, I know it is a 4.2 camera but the 4.2 camera has been ported to JB 4.1 many times on other devices and since there are many more users of JB4.1 ROMs than 4.2, I thought I might as well get the test out of the way.....
Eventually I was able to get it to work. I wasn't able to install it using the flashable zip...it may be the recovery I am using (it is Thomas1991_12's dual recovery with TWRP and CWM...neither would install the zip). So I manually installed Gallery2.apk and the library files (set permissions to 644) and the camera is working. The videorec FCs when you stop recording (saves the video though!). Panorama is also FCing...but I believe this is common when putting the 4.2 camera onto JB4.1 based ROMs....also the Forward Facing camera is FCing but I believe this also may be a bug in the AOKP ROM I am using. Unless some one else reports for a 4.2 ROM, I will test it out later today...
I attached two logcats, one for the viderec crashing and one for the panorama crashing....
Thanks a lot for this!
EDIT: forgot to mention that the zip appears to load correctly (doesn't throw any errors) but the new gallery does not appear in /system/app....
