Android sqlite3 Tuto
===

when i googling it i don't ind anything relevant so may be you have something for my guys.

So i have a database named :
>db.sqlite3 

And i work on a android project.I need to o some query on it.

I have a lot of question about it so if you know a good tutorial let me know.

Or this is my most important question :

where did i put the database ? (it's not to big so in the project but which folder?)

How i do a query ? 

Thank in advance.
