La contrainte UNIQUE a échoué: la base de données sqlite : android

Je suis en train d'insérer des valeurs dans le tableau. Mais il y a une seule valeur insérée. J'obtiens une erreur dans le journal de chat lorsque j'essaie d'insérer de nouvelles valeurs.

Journal des spectacles de chat :

Sa montre l'erreur sur ces deux lignes lors de l'insertion de la ligne.
