When is a SQLite database initially created in Android?

I am familiar with the notion of the SQLiteOpenHelper class and its onCreate & onUpgrade method, but when is the database itself actually instantiated for the first time? Is it during installation of the app, or upon the first call of getWritableDatabase()/getReadableDatabase() ?

Thanks!

Database, as file on disk, is created when you call getWritableDatabase or getReadableDatabase.

Just read the docs of SQLiteOpenHelper constructor ;-)

No.

Yes. This is why it is important to call those methods on a background thread, as how long they take depends upon whether or not the database needs to be created or upgraded.
