OK, so apparently I got myself in over my head. I'm pretty sure I followed the directions to the letter. Copied GalleryGoogle.apk and GMSCore.apk to the system>apps folder, changed permissions to RW-R-R (did NOT install). Copied libjni_filtershow_filters.so and libjni_mosaic.so and liblightcycle.so to the system>lib folder (is that right? not sure), changed permissions to RW-R-R, rebooted a couple times.
But whenever I try to open the camera or the gallery, I get the "Unfortunately, Gallery has stopped working" error. What did I miss? (Keep in mind that, like I said earlier, I'm in way over my head here. Explain it to me as if you were explaining it to your grandfather or a particularly stupid cousin.)
Thanks for any help.
