Where does Android (Cordova) memory go?

Question

JavaScript

I am writing a simple application. I am using the crosswalk plugin.
I get data from json server. I don't write them anywhere. I am using localStorage to store two variables. The question is where does the memory go?
Where did 11.6 mb of data come from?

Answer 1

If the device is rooted, then you can see what exactly the application stores in/data/data/packagename

Answer 2

It's a .dex cache (also known as a dalvik cache) most likely.

Answer 3

Well, first of all, do not forget that your application is a bowser. What storage needs does the browser have? History, css and js cache, and other needs
