Android: After creating a new notification, the older one is replaced

Question

I want to create a notification without canceling/deleting previous notifications from my app. Here is my code for creating a notification:

private void notification(Context context, String title, String content) {     NotificationCompat.Builder mBuilder =             new NotificationCompat.Builder(context)             .setSmallIcon(R.drawable.notification_icon)             .setContentTitle(title)             .setContentText(content);      Intent resultIntent = new Intent(context, MainActivity.class);     TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);     // Adds the back stack for the Intent (but not the Intent itself)     stackBuilder.addParentStack(MainActivity.class);     // Adds the Intent that starts the Activity to the top of the stack     stackBuilder.addNextIntent(resultIntent);     PendingIntent resultPendingIntent =             stackBuilder.getPendingIntent(                 0,                 PendingIntent.FLAG_UPDATE_CURRENT             );     mBuilder.setContentIntent(resultPendingIntent);     NotificationManager mNotificationManager =         (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);     //Id allows you to update the notification later on.     mNotificationManager.notify(100, mBuilder.build()); } 

Answer 1

You are using a hardcoded id for your notification, of course it will replace the old one. Try using a variable ID instead of a hardcoded 100.

mNotificationManager.notify(100+x, mBuilder.build()); 

or something of the sort.

Answer 2

Use variable id for notification, I have faced this issue 1 Hour ago And used this technique to overcome this issue.

        val id= Random(System.currentTimeMillis()).nextInt(1000)         mNotificationManager?.notify(id, mBuilder.build())
