Échec de la création de la base de données SQLite dans mon appareil Google Nexus One sous Android?

Question

Je travaille sur une application dans laquelle je crée ma base de données sqlite locale, et son fonctionnement avec succès dans tous les appareils, sauf le Google Nexus One avec OS 2.3.3. Journaux:

Answer 1

Si ce fichier de base de données particulière fonctionne partout, sauf dans les anciennes versions d'Android, alors il est probable que vous utilisez une fonction SQLite qui ne sont pas disponibles dans la version plus SQLite.

par exemple, WAL est prise en charge en commençant par SQLite 3.7, mais Froyo a SQLite 3.6.22.
