This repository accompanies a blog post I wrote on Android Design Patterns on animated icons.

It contains over 25 AnimatedVectorDrawables that you can refer to free of charge. You know... cool animated icons like these!

Additional icon implementations are welcome if you've written anything cool that you want to share... submit a pull request! :)

Some notes on backwards compatibility

This sample app uses a minSdkVersion of 21. However, there is a good amount of stuff in here that could still be used on older platform versions:

  1. VectorDrawableCompat and AnimatedVectorDrawableCompat can for the most part be used on pre-Lollipop devices with a couple of restrictions (continue reading below). Read Chris Banes' blog post for more information. Note that even though this app uses a minSdkVersion of 21, it is still advantageous to use the VectorDrawableCompat support library implementation (as it fixes some framework bugs that existed on API versions 21-23).

  2. Specifying tints, tint modes and/or theme attributes in VectorDrawable XML is supported on all platform versions. Read this blog post for more information.

  3. AnimatedStateListDrawable is not supported on pre-Lollipop devices. However, it is only being used in this project for convenience and is not strictly required (not using it just means you'll need to manually start the AnimatedVectorDrawables yourself).

  4. Using the android:property{X,Y}Name attributes in an ObjectAnimator's XML is not supported on pre-Lollipop devices. These new attributes correspond to the ObjectAnimator#ofFloat(Object, String, String, Path) method, which was only added in API 21.

  5. Using the new material design interpolators (such as @android:interpolator/fast_out_slow_in, etc.) is not supported on pre-Lollipop devices. However, you can create your own custom PathInterpolators using the support library.

Known issues

  • On Android 5.0 and 5.1, some icons appear blurry and aren't tinted properly. See this bug thread for more information.
