Android's animated fingerprint icon provided in a simple, standalone library.

Since Swirl uses animated vector drawables, default colors cannot be provided and must be specified in your theme.

<style name="Theme.YourApp" parent="@android:style/Theme.Material.Light">
  <item name="swirl_ridgeColor">?android:attr/textColorSecondary</item>
  <item name="swirl_errorColor">?android:attr/colorAccent</item>
</style>

Then, you may include SwirlView anywhere in your app.

<com.mattprecious.swirl.SwirlView
    android:layout_width="60dp"
    android:layout_height="60dp"
    />

Note that this example specifies a width and height and does not use wrap_content. Since the drawables are vectors, there isn't an appropriate size to default to so you must specify one.

Switch between icons by calling setState() or by using the app:swirl_state attribute.

See the provided sample for a complete implementation.
