Advice Request Understanding Smali files

[saneeha]

I am working on analysis of android malware. I have dis-assembled apks using apktool.
Now i m unable to understand the correspondence between the android classes and smali files..

Please help me in understanding that how many smali files are generated against an application and
do smali only refer to classes.dex code. I have only two classes in my application and too many smalis
are present in the decompiled application.

Your help is highly appreciated
