getBigPicture

Loads and returns the big picture image for expanded notification style.

This method downloads the image from the URL specified in the push payload's "pw_big_picture" attribute. The image is displayed when the user expands the notification. This method runs on a worker thread, so network operations are safe.

Image Requirements:

• Recommended size: 2:1 aspect ratio (e.g., 1024x512)
• Supported formats: JPEG, PNG
• The image should be optimized for mobile

Override this method to customize image loading, such as using a different image library (Glide, Picasso), applying transformations, or loading from local storage. Example - Custom image loading with caching:

	  
	  protected Bitmap getBigPicture(PushMessage pushData) {
	      String imageUrl = pushData.getBigPictureUrl();
	      if (imageUrl == null) {
	          return null;
	      }
	
	      try {
	          // Use Glide with caching
	          return Glide.with(getApplicationContext())
	              .asBitmap()
	              .load(imageUrl)
	              .submit(1024, 512)
	              .get();
	      } catch (Exception e) {
	          Log.e("NotificationFactory", "Failed to load big picture", e);
	          return null;
	      }
	  }
