J'essaie de tester une notification. J'ai créé un émulateur avec la lecture audio activée. Je suis en mesure d'obtenir la notification, mais je ne suis pas en mesure d'entendre le son. Quel pourrait être le problème? Y a-t-il des paramètres qui me manquent?Problème avec les sons de notification
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(ns);
int icon = R.drawable.icon;
CharSequence tickerText = "Hello";
CharSequence contentTitle = "My notification"; // expanded message title
CharSequence contentText = "Hello"; // expanded message text
Intent notificationIntent = new Intent("ABC");
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, tickerText, when);
notification.defaults |= Notification.DEFAULT_SOUND;
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
mNotificationManager.notify(HELLO_ID, notification);
Lorsque j'ai vu logcat, j'ai la trace de pile suivante.
