Bonjour,

Pourquoi dès l'utilisation du spinner et d'un DatePickerDialog., ça plante et m'indique cette erreur dans le logcat:

06-14 10:46:44.253: ERROR/AndroidRuntime(2994): android.view.WindowManager$BadTokenException: Unable to add window -- token android.app.LocalActivityManager$LocalActivityRecord@40532780 is not valid; is your activity running?

Merci.
