One content provider for all your tables works fine.
I don't know if that's the best way to do it but i'm using a content
provider as a dao container managing the state of my database connection and
providing access to DAOs that are responsible each of them of one table.
Besides, each DAO extends a GenericDAO<T> abstract class that provide access
to a T type of objects.
class userDAO extends GenericDAO<User> { ...}
and for the code that is similar i'm putting it in a GenericDAO with some
hook that are to be implemented by each DAO.
abstract T createObjectFromCursor(Cursor cursor);
abstract String[] getColumnNames();
abstract String getTableName();
abstract ContentValues getContentValuesForObject(T);
The generic DAO provide some utils methods like public T findObjectById(long
id)
or ArrayList<T> findObjectsListByWhereClause(string where, ArrayList<T>
list);
And some others...
