所以这是我的alaram接收，它在应用程序被杀死时没有问题，通知被解雇，一切似乎都很好。
public class AlarmReciever extends BroadcastReceiver {
private CharSequence msg = "Notofication";
@Override
public void onReceive(Context context, Intent intent) {
Log.i("Alarm reciever", "Reached");
String sationSelected = intent.getStringExtra("SationSelected");
Log.i("slected is :", sationSelected);
Intent serviceRadio = new Intent(context, RadioService.class);
serviceRadio.putExtra("SationSelected",sationSelected);
context.startService(serviceRadio);
Intent dismissIntent = new Intent(context,DismissBroadcast.class);
dismissIntent.putExtra("Notification ID",1);
PendingIntent piDismiss = PendingIntent.getBroadcast(context, 100, dismissIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder =
new NotificationCompat.Builder(context)
.setOngoing(true)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("Radio station playing")
.setAutoCancel(true)
.setContentText("Radio station playing content")
.setPriority(Notification.PRIORITY_MAX)
.setDefaults(Notification.DEFAULT_ALL)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(msg))
.addAction(R.mipmap.ic_launcher_round,
"Stop Radio", piDismiss);
NotificationManager manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(1, builder.build());
Log.e("You are at the","Receiver");
}
}
这是我的服务，我删除了一些站点，但留下了一些让你知道我在做什么，当应用程序被杀死时，这个服务似乎没有加载URL。如果app没有被杀死，那么这项服务工作正常。

答案 0 :(得分：0)
我的预感是我的服务没有被调用。
CREATE TABLE Remaingdays1
(
id INT NOT NULL PRIMARY KEY,
SDate DATE,
EDate Date,
remaingdays as SDate-EDate-- This should be the resultant of days
);
和onStop()放置日志，然后检查您的日志
还在onDestroye() 我已经在我的服务中实施了一个唤醒锁，但仍然没有快乐。 我还为媒体播放器实现了自己的唤醒锁定 仍然没有快乐。
无需实施唤醒锁定，只要服务正在运行，音乐就会播放
您也可以为音乐播放器学习GoogleProject。
