Errore nella creazione del database SQLite

**dvdciri** · 04-11-13 14:59

Ciao ragazzi sto creando un database SQLite interno all'applicazione, ho creato la pagina che conterrà tutte le specifiche del database e le query varie, provando a fare un insert noto che non mi da un errore "No such table..." e noto anche che non trova la tabella in quanto non fa partire proprio la query di create table nel metodo onCreate. Le ho provate tutte ci deve essere qualcosa che manca o che ho sbagliato mi date una mano? grazie

Questo è il file del database:

codice:

Questo è l'errore:
