This gist is an example of the new Android XML bundle format which lets you create more succinct AnimatedVectorDrawables.

Previously to create an AnimatedVectorDrawable you would need at least 3 xml files to specify it:

  1. A VectorDrawable you're going to animate.
  2. One or many Animators to run.
  3. An animated-vector definition, essentially tying the drawable and animator(s) together.

The new bundle format lets you specify this in a single file. Notice the aapt namespace and usage; at build time, aapt will create the separate resources for you (1 & 2 in the list above) and reference them in the animated-vector. This requires Build Tools 24+ (currently in RC) but the output is backward compatible.

After a bunch of trial and error, the only time Animated Vector Drawables seem to work is if I use android:src on the ImageView and not app:srcCompat But there seems to be a huge difference in the rendering. The latter actually looks like a vector while the former looks like a very low res image.

As another form of trial I added
static { AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); }
and it still didint make a difference

How do I achieve high res animated vector?

Wow, this is great! I first didn't get it to work because I did not upgrade my Build Tools to 24+. After reading the post again I see that Nick already mentioned it. Thanks.

I'm still getting a "Attribute missing on Android namespace" for line Line 22 which if I resolve compounds to error at the line in the beginning - 1. requires api 21 2. animated-vector doen't have required attribute android:drawable
AS 2.2.2
Build tool 25.0.0
Gradle Plugin 2.2.2

Getting the same problem as nycodes9. Anyone find a solution to this?

Found a decent example of how to get this working: https://blog.stylingandroid.com/animatedvectordrawable-bundles/

There were some missing attributes in the provided example above.
