Where can I find SharedPRefs file on my MotoG device ? It is with KitKat BTW Generally for SharedPRefs file the path is like : data/data/com....application..package..name/shared_prefs/filename.xml. 

But when I tried to navigate through the same path on my MotoG device, I don't see anything like this after 

/data/..... :(

Can you guys help me please....
This is because your phone is not rooted. By default, only the application itself can access files in /data/data/com.whatever, so that casual users don't edit the files and break the app. To see these files, you need to root the device and use a file explorer tool that can use root (this is usually called a "root explorer" app or feature).
