db.execSQL(

		         task_name + "text,"  +
		         task_complete +  "text);" 
 
		         );

Relis bien ton code !

[bibmanhjp]

bonjour,
l'erreur c'est pas l'ID ?

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

public static final String task_id ="id";

mais plutot :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

public static final String task_id ="_id";

juste il manque le _ !!
je suis débutant aussi mais je croie que c'est obligatoir sous SQLite !

[samaury]

Comme dis nicroman, "relis bien ton code" et rajoutes un espace après le "Create table "

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
db.execSQL(
		         "create table "+ TASKS_TABLE

en non

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
db.execSQL(
		         "create table"+ TASKS_TABLE

Il y a 5 fois la même erreur...
