I decompiled an Apk file and I want to add some code to the java classes,but it seems that the javaclasses are different from the way they are written,for example those who edit WhatsApp and make WhatsApp plus ,how did they decompile WhatsApp to get dull source code and add some java codes to add features ?really frustrating !

The apk is most likely obfuscated with some program such as proguard because the developers do not want you looking at their source code..
