setBanner

open fun setBanner(url: String): LocalNotification.Builder

Sets a large image to be displayed in the notification using Android's BigPictureStyle.

The banner image is displayed when the notification is expanded and provides a rich visual experience. The image is downloaded and cached when the notification is displayed. Example: 


		  // E-commerce flash sale with product image
		  LocalNotification saleNotification = new LocalNotification.Builder()
		      .setMessage("50% off on selected items!")
		      .setBanner("https://cdn.example.com/flash-sale-banner.jpg")
		      .setLink("myapp://sale")
		      .setDelay(3600)
		      .build();
		
		  // News article with feature image
		  LocalNotification newsAlert = new LocalNotification.Builder()
		      .setMessage("Breaking: Major event update")
		      .setBanner("https://news.example.com/article-image.jpg")
		      .setLink("newsapp://article/12345")
		      .setDelay(1800)
		      .build();
		
		  // Fitness achievement with motivational image
		  LocalNotification achievement = new LocalNotification.Builder()
		      .setMessage("Congratulations! You reached your goal!")
		      .setBanner("https://cdn.fitnessapp.com/achievement-badge.png")
		      .setDelay(7200)
		      .build();
