getLargeIcon

Loads and returns the large icon image for the notification.

The large icon appears on the right side of the notification (or left on some devices) and provides a visual identifier for your app or the notification content. This method downloads the image from the URL specified in the push payload's "pw_large_icon" attribute.

The image is automatically sized to match the system's notification_large_icon_height dimension (typically 64dp x 64dp). This method runs on a worker thread, so network operations are safe.

Image Requirements:

• Recommended size: 256x256 (will be scaled down)
• Should be square or circular
• Supported formats: JPEG, PNG
• Transparent backgrounds work well

Override this method to customize image loading or apply circular cropping, rounded corners, or other transformations. Example - Custom image with circular crop:

	  
	  protected Bitmap getLargeIcon(PushMessage pushData) {
	      String iconUrl = pushData.getLargeIconUrl();
	      if (iconUrl == null) {
	          // Fall back to app icon
	          return BitmapFactory.decodeResource(
	              getApplicationContext().getResources(),
	              R.drawable.ic_launcher
	          );
	      }
	
	      try {
	          // Load and apply circular transformation
	          Bitmap bitmap = Glide.with(getApplicationContext())
	              .asBitmap()
	              .load(iconUrl)
	              .transform(new CircleCrop())
	              .submit(256, 256)
	              .get();
	          return bitmap;
	      } catch (Exception e) {
	          Log.e("NotificationFactory", "Failed to load large icon", e);
	          return null;
	      }
	  }
