How to create multiple notification?

Question

This is my MyReceiver.java class and here i have written a code to display single notification. How to create multiple notification here.

         public class MyReceiver extends BroadcastReceiver{
String Reqpopending;
int MID=0;
@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub


    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(context, SplashScreen.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
            context).setSmallIcon(R.drawable.dashboard)
            .setContentTitle("Dash Board Counts")
            .setContentText("P.O Counts-532,198,654,255,901 ZeroInward-303 PartialInward-777").setSound(alarmSound)
            .setAutoCancel(true).setWhen(when)
            .setContentIntent(pendingIntent)
            .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
    notificationManager.notify(MID, mNotifyBuilder.build());


    MID++;

}

Please find below the code which is being run in the loop

public class MyReceiver extends BroadcastReceiver{
String Reqpopending;
int MID=0;
@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub

    for(int i = 0; i < 3; i++)
    {
    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(context, SplashScreen.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);


    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
            context).setSmallIcon(R.drawable.dashboard)
            .setContentTitle("Dash Board Counts")
            .setContentText("P.O Counts-532,198,654,255,901 ZeroInward-303 PartialInward-777").setSound(alarmSound)
            .setAutoCancel(true).setWhen(when)
            .setContentIntent(pendingIntent)
            .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});
    notificationManager.notify((int)when, mNotifyBuilder.build());
    }

}

Hope this helps.

public class NotificationId {
 private final static AtomicInteger c = new AtomicInteger(0);
    public static int getID() {
        return c.incrementAndGet();
    }

 }
 notificationManager.notify(NotificationId .getID(), mNotifyBuilder.build());

AtomicInteger guarantees a unique integer every time your code is right, but there is minor bug somewhere, so it does work for multiple notification. This code is works for me, so you can try.

in this line of code

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

you have to give different request codes like

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
                notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 1,
                notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 2,
                notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 3,
                notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

If you truly need multiple distinct PendingIntent objects active at the same time (such as to use as two notifications that are both shown at the same time), then you will need to ensure there is something that is different about them to associate them with different PendingIntents. This may be any of the Intent attributes considered by {@link Intent#filterEquals(Intent) Intent.filterEquals} , or different request code integers supplied to {@link #getActivity} , {@link #getActivities} , {@link #getBroadcast} , or {@link #getService} .
