Android通知不会发出声音或振动

Question

int icon = R.drawable.icon;  
Context context = getApplicationContext();    
CharSequence contentTitle = "My notification";  
CharSequence contentText = "Countdown Complete!";     
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Intent intent = new Intent();
Notification notification = new Notification(icon, "is completed!", System.currentTimeMillis());  
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
notification.setLatestEventInfo(context, contentTitle, contentText, pendingIntent);
long[] vibrate = {0,100,200,300};
notification.vibrate = vibrate;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND; 
notificationManager.notify(myCountDown.getId(), notification);

这个代码在我的Android应用程序中,我收到通知但没有声音或振动.

我已经在多部手机上进行了测试,声音和振动都在设置中打开和关闭.我也确定我要求在android清单中使用振动许可但我仍然只收到通知......

我也尝试过:

notification.defaults = Notification.DEFAULT_ALL;

和

notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.defaults |= Notification.DEFAULT_LIGHTS;
notification.defaults |= Notification.DEFAULT_SOUND;

如何在通知中获得声音和振动？

不要忘记启用铃声和通知的振动设置.转到设置 - >声音.检查"声音振动".
