【问题描述】：
所以这是我的警报接收，当应用程序被杀死时它可以正常工作，通知被触发并且一切看起来都很好。
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，但留下了一些让您了解我在做什么，当应用程序被终止时，此服务似乎没有加载 URL。如果应用没有被杀死，那么这个服务就可以正常工作。
