Decompile and Recompile apk files on ubuntu

I am trying to modify an Android app using apktool.

I've downloaded the apktool and now I have 3 file apktool, aapt and apktool.jar

I am trying to modify the background of the Gallery_3D.apk

I am using these command to decompile and then recompile

./apktool if Gallery 3D.apk
./apktool d Gallery 3D.apk gallery

It works fine for above 2 steps but while recompiling using command

./apktool b gallery Gallery 3D New.apk

However I am getting this error in the last step.

I: Checking whether sources has changed...
I: Smaling...
I: Checking whether resources has changed...
I: Building resources...

I know this is quite old answer, but I'm going to post the solution in case somebody still need help.

The first problem, was pointed out by RC: you need to add aapt to your path. You can do this with the following command:

PATH=$PATH:/location/of/aapt

To fix the second problem (INSTALL_PARSE_FAILED_NO_CERTIFICATES), you need to sign your apk. You can do this using testsign.jar:

java -jar testsign.jar unsigned.apk signed.apk
