How to display multiple notifications in android

Question

I am receiving only one notification and if there comes another notification, it replaces the previous one and here is my code

private static void generateNo         


        

Answer 1

Another way of doing it is take the current date convert it into long just take the last 4 digits. There is a high probability that the number will be unique.

    long time = new Date().getTime();
    String tmpStr = String.valueOf(time);
    String last4Str = tmpStr.substring(tmpStr.length() -5);
    int notificationId = Integer.valueOf(last4Str);

Answer 2

notificationManager.notify(0, notification);

Put this code instead of 0

new Random().nextInt() 

Like below it works for me

notificationManager.notify(new Random().nextInt(), notification);

Answer 3

For Kotlin.

 notificationManager.notify(Calendar.getInstance().timeInMillis.toInt(),notificationBuilder.build())

Answer 4

At the place of uniqueIntNo put unique integer number like this:

mNotificationManager.notify(uniqueIntNo, builder.build());

Answer 5

Below is the code for pass unique notification id:

//"CommonUtilities.getValudeFromOreference" is the method created by me to get value from savedPreferences.
String notificationId = CommonUtilities.getValueFromPreference(context, Global.NOTIFICATION_ID, "0");
int notificationIdinInt = Integer.parseInt(notificationId);

notificationManager.notify(notificationIdinInt, notification);

// will increment notification id for uniqueness
notificationIdinInt = notificationIdinInt + 1;
CommonUtilities.saveValueToPreference(context, Global.NOTIFICATION_ID, notificationIdinInt + "");
//Above "CommonUtilities.saveValueToPreference" is the method created by me to save new value in savePreferences.

Reset notificationId in savedPreferences at specific range like I have did it at 1000. So it will not create any issues in future. Let me know if you need more detail information or any query. :)

A simple counter may solve your problem.

private Integer notificationId = 0;

private Integer incrementNotificationId() {
   return notificationId++;
}

NotificationManager.notify(incrementNotificationId, notification);
