Question

我是android开发新手，我正在创建一个应用程序，您可以在其中标记您的出勤率，因此，当出勤率低时，它会发送通知，我写下面的代码

private void setup(final String keys, final int uid, final String x) {
    final int[] uid0 = {uid};
    br = new BroadcastReceiver() {

        @Override

        public void onReceive(Context c, Intent i) {

            NotificationCompat.Builder notf;
            uid0[0] += 1;
            notf = new NotificationCompat.Builder(see.this);
            notf.setAutoCancel(true);
            notf.setSmallIcon(R.mipmap.ic_launcher);
            notf.setTicker("Your attendance is low!!");
            notf.setWhen(System.currentTimeMillis());
            notf.setContentTitle("Your "+keys+" attendance is low !!");

            notf.setContentText("It is "+x+" %");
            Intent inte = new Intent(see.this,see.class);
            PendingIntent penin= PendingIntent.getActivity(see.this,0,inte,PendingIntent.FLAG_UPDATE_CURRENT);
            notf.setContentIntent(penin);
            NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            nm.notify(uid,notf.build());

        }

    };

    registerReceiver(br, new IntentFilter("com.ajaypilaniya.omg"));

    pi = PendingIntent.getBroadcast( this, 0, new Intent("com.ajaypilaniya.omg"),
            0 );

    am = (AlarmManager)(this.getSystemService( Context.ALARM_SERVICE ));

}

这是定义通知属性的设置功能。在课堂上我有这些行

final long ONE_SECOND = 1000;

final long TWENTY_SECONDS = ONE_SECOND * 10;

PendingIntent pi;

BroadcastReceiver br;

AlarmManager am;

setup(keys,uid,kk);
                am.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime() +
                        TWENTY_SECONDS, pi);

在android清单中我添加了这些行

 <user-permission android:name="android.permission.WAKE_LOCK"/>
<user-permission android:name="com.android.alarm.permission.SET_ALARM"/>`

但是当我关闭应用程序时，它在10秒后没有显示通知，那么怎么做呢？在某处我读到我们需要在清单中为广播接收器添加代码，但我不知道该怎么做？

应用关闭时通知未显示：Android
