答
您的活动，请执行以下操作来启动服务。例如，在的onCreate（）：
Intent intent = new Intent(this, MyService.class);
startService(intent);
在你的服务，请在的onCreate（）如下：
int NOTIFICATION_ID = 2707;
NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
builder.setSmallIcon(android.R.drawable.ic_menu_info_details)
.setContentTitle("MyAppName")
.setContentText("the service is running!")
.setTicker("the service is running!")
.setOnlyAlertOnce(true)
.setOngoing(true)
.setSound(alarmSound);
Notification notification = builder.build();
startForeground(NOTIFICATION_ID, notification);

只是隐藏stopSelf（）;和_shutdownService（）;或尝试WakefulBroadcastReceiver方法

您需要使用前景的服务http://*.com/questions/24839655/how-to-use-startforeground/24839801#24839801 –
这个已经完成，但仍是问题是一样的。 – vickyVick
尝试在'onStartCommand（...）''onStartCommand（...）'函数中返回'START_STICKY' –
