How to create group push for android 4.4.2? -


i want create group push same notification. code works on android 7.0, doesn't worked android 4.4.2.

private static int notification_id = new random().nextint();  private void sendandroidnoticiation(intent[] intents, string title, string text, bitmap image, string group) {      if (image == null) image = bitmapfactory.decoderesource(getresources(), r.mipmap.ic_launcher);      pendingintent pendingintent =             pendingintent.getactivities(this, ++notification_id, intents, pendingintent.flag_one_shot);      uri uri = ringtonemanager.getdefaulturi(ringtonemanager.type_notification);      notificationcompat.builder mbuilder = new notificationcompat.builder(this)             .setsmallicon(r.drawable.ic)             .setlargeicon(image)             .setcontenttitle(title)             .setcontenttext(text)             .setsound(uri)             .setautocancel(true)             .setcontentintent(pendingintent)             .setsmallicon(r.drawable.ic)             .setcategory(notification.category_event)             .setgroupsummary(false)             .setgroup(group);     notificationmanagercompat mnotifymgr = notificationmanagercompat.from(getapplicationcontext());     mnotifymgr.notify(notification_id, mbuilder.build());     showgroupsummarynotification(mnotifymgr, group); }  private void showgroupsummarynotification(notificationmanagercompat notificationmanager, string group) {     notificationcompat.builder builder = new notificationcompat.builder(this)             .setstyle(new notificationcompat.inboxstyle())             .setnumber(2)             .setsmallicon(r.drawable.ic_nim_big_white)             .setcategory(notification.category_event)             .setgroupsummary(true)             .setgroup(group);     notification notification = builder.build();     notificationmanager.notify(123456, notification); }

i have seen such questions:

  1. android: grouped notifications , summary still shown separately on 4.4 , below
  2. stack notifications in kitkat (api 19) using setgroup() not working
  3. what purpose of setgroup() in notification.builder?

but did not me.
