arapk is very simple automaton script for decompiling, recompiling, generating the keystore and signing the APK with specified keystore arguments.
python arapk.py -g <Keystore_name> #Generate user based keystore name
python arapk.py -n <keystore_name> -s <path_to_apk> #sign the modified apk using the generated keystore
python arapk.py -d <path_to_apk_decompile> #decompile the apk file
python arapk.py -r <path_to_folder_to_recompile> #recompile the modifed folder back to apk
'python 2.7', 'jarsigner', 'keytool' and "apktool.jar" to be present and set appropriately in environment path. [This process will also be automated soon]
[Expect bugs. This is just beta phase] [Warning : For educational purpose only]
[More documentation coming soon....]
