Imported Sqlite Database not working in Android -

-

I am struggling with database import for a short while on my Android project, I'm new to Android. That's what Android supports Skylite, so my first question is, I have to remove the .sqlite extension and replace it with DD, for example since I found it on the net, I only saw .db extension files After doing this, I put my existing database file in my property folder and use a class to manage my database.

This tutorial I am doing:

In the tutorial, it says that I have to designate all the ID columns in _id, is it mandatory?

The extension may be anything (better .db). _ _ Field is not mandatory.
I have the strength of my DB without any DD> All (in fact)

I call the ID field, whatever I want.
I need a special method for this, the _id field is required, then I use duplicate using the rowID As _id move
rowID is a special "hidden" field that actually treats such as it was the _id field.
