if want use heads-up notifications this:

enter image description here

set notification priority notification.priority_high or notification.priority_max

notificationcompat.builder builder = new notificationcompat.builder(this);             builder.setsmallicon(r.drawable.ic_wald_poi)                     .setlargeicon(bitmapfactory.decoderesource(getresources(), r.drawable.ic_poi))                     .setcolor(getresources().getcolor(r.color.primary))                     .setcontenttitle(getstring(r.string.hello))                     .setcontentintent(notificationpendingintent)                     .setcontenttext(string.format(getstring(r.string.notification), viewobject.gettitle()))                     .setdefaults(notification.default_all)                     .setstyle(bigtext)                     .setpriority(notification.priority_high);
