Thanks xavierjohn22, finally got it working.
I was struggling to get my wallpapers to work without getting
them cropped.
I'm new to android, coming from Windows 6.5, and it was really frustrating
not to been able to use wallpapers, as I have been using on my windows phone, without it getting cropped.
But now with your amazing tool, I can make my own wallpapers.apk,
and pick my wallpapers from menu-->Backgrounds-->GbNoR Wallpapers.
What I did:
*Put the ELWallpapers.apk (extracted from the rom to Elelinux) in
the _INPUT_APK folder.
*Decompile ELWallpapers.apk (*6*)
*Edit every file, folder, xml and smali. I just replaced the text Elelinux/ELWallpapers
with GbNoR/GBWallpapers
*Replaced the wallpapers and icon with my own.
Note: had to remember small letters (low case) for the icons and
wallpapers in the "drawable-mdpi" folder.
*Recompile the ELWallpapers folder (*7*)
*Closed the log, open the folder "dist"
(_INPUT_APK-->ELWallpapers-->dist)
*Now I had to sign the apk in the "dist" folder (*10*)
*Put the ELWallpapers_Signed.apk on my sdcard and install it.
Here is the result
