Bonjour à toutes et à tous,
J'ai suivit la documentation officiel d'Android sur le site officiel pour créer une notification (source : https://developer.android.com/guide/...leNotification)

J'ai donc fait un test de mon application et aucun soucis mais dès que je veux le faire sur un Android 8 le drame... Celà m'affiche ceci :


Je ne comprends pas du tout j'ai suivit le guide officiel à la lettre... Voici mon code :

protected void sendNotification(String itemName) {
 
        // The id of the channel.
        String CHANNEL_ID = "plop";
        NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(this, CHANNEL_ID)
            .setSmallIcon(R.drawable.ic_menu_share)
            .setContentTitle("Objet trouvé")
            .setContentText("" + itemName);
 
        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(this, TrainingActivity.class);
 
        // The stack builder object will contain an artificial back stack for the
        // started Activity.
        // This ensures that navigating backward from the Activity leads out of
        // your app to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(TrainingActivity.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
 
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
 
        // mNotificationId is a unique integer your app uses to identify the
        // notification. For example, to cancel the notification, you can pass its ID
        // number to NotificationManager.cancel().
        mNotificationManager.notify(101, mBuilder.build());
    }

Merci beaucoup de votre aide car je suis perdu

P.S: j'ai même essayé ceci sans succès :
