 InputStreams are closed automatically in finalizer if GifDrawable is no longer needed 
 so you don't need to explicitly close them. Calling `recycle()` will also close

 Normally single `GifDrawable` instance associated with multiple `View`s will animate only on the last one.
 To solve that create `MultiCallback` instance, add `View`s to it and set callback for given drawable, eg.:
 ```java
-	MultiCallback multiCallback = new MultiCallback();
+MultiCallback multiCallback = new MultiCallback();
 
-    imageView.setImageDrawable(gifDrawable);
-    multiCallback.addView(imageView);
+imageView.setImageDrawable(gifDrawable);
+multiCallback.addView(imageView);
 
-    anotherImageView.setImageDrawable(gifDrawable);
-    multiCallback.addView(anotherImageView);
+anotherImageView.setImageDrawable(gifDrawable);
+multiCallback.addView(anotherImageView);
 
-    gifDrawable.setCallback(multiCallback);
+gifDrawable.setCallback(multiCallback);
