Reading from assets directs to wrong path?

I'm trying to use sqlite helper class, I have my db_map at /assets folder. sqlite helper should copy it from there to data/data/http://ift.tt/1FKBCa3

what happens is that I get a FileNotFound exception.

While debugging and using assetManager.list(""). I found that I have "images", "sounds", "webkit" files in the list. what is weird is I don't have those and only my db_map file.

code :

AssetManager assetManager = context.getResources().getAssets();
myInput = assetManager.open("db_map");
