 If you use `LottieDrawable` directly, you must call `recycleBitmaps` when you are done with it.
 
+If you need to provide your own bitmaps if you downloaded them from the network or something, you
+ can provide a delegate to do that:
+ ```java
+animationView.setImageAssetDelegate(new ImageAssetDelegate() {
