SQLite unable to open database file (code 14) on frequent “SELECT” query

Question

I have following class \"Singleton\" to handle SQLite connection and to make sure to have 1 instance of connection for whole process/app:

public class DBCon         


        

Answer 1

Your code re-opens the database every time dbOpen() is called.

An SQLite database object is quite lightweight; it does not really make sense to keep closing and re-opening it.

You already have your singleton; just store a single SQLiteDatabase reference there.
