A simple and small python script to call dex2jar and then cfr or procyon.
It takes as an argument an apk which is converted to the corresponding jar files from dex2jar and then depending on your choice cfr or procyon decompile it to Java.
$ python3 lazyX -d procyon basic.apk
dex2jar ----> Converting...
dex2jar basic/classes.dex -> basic/classes.jar
procyon ----> Decompiling...
Completed!
As you would add any script to your path you can put lazyX for example in /usr/local/bin.
You can run something like the following from within the repo after you have download it.
sudo mv libs lazyX /usr/local/bin && sudo chmod +x /usr/local/bin/lazyX
Do remember to update the shebang line depending on your environment!
If you would like to update the versions of dex2jar and cfr that are being used by the script then all you have to do is delete and replace the directory dex-tools-2.2-SNAPSHOT with the new version of dex2jar downloaded from here and also replace the cfr and procyon jar files with the new ones you would like.
As a final step you have to update the following three variables in the script accordingly:
name_of_the_DEX2JAR_directory = "libs/dex-tools-2.2-SNAPSHOT"
name_of_the_cfr_jar = "libs/cfr-0.152.jar"
name_of_procyon_jar = "libs/procyon.jar"
