Help- Not able to sucessfully recompile samsungcamera apk

Hi.
I extracted samsungcamera from qsrom 4.4.2 i9300 nl1, and decompiled it using apktool.
then I modified smali files and replaced
"com.sec.android.gallery3d" to "com.alensw.PicFolder"
"com.sec.android.gallery3d.app.Gallery" to "com.alensw.PicFolder.GalleryActivity"

but after recompiling it with some error I got new modified class ,resourceses, and other xmls,
then I opened original samsungcamera.apk and replaced inside with new class, recources and xmls, and then pushed new samsungcamera.apk in system app gave proper permissions , installed quickpic and restarted,
after restart camera icon shows in app drawer but when opened it force-closes.

if someone with knowledge could could modify samsungcamera the it would be great help, ThankYou
