In the <objectAnimator tag, you need the repeat* attributes

<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:valueTo="200"
    android:valueType="floatType"
    android:propertyName="y"
    android:repeatCount="1"
    android:repeatMode="reverse"/>

In that case, you'd need to manually make you application repeat using other ObjecAnimator. Since the splash screen is supposed to be short lived, an animation shouldn't need to be repeated. If the loading time of your application is too high and require the use of some progress indicator, then I suggest to implement that in the app directly, ideally using skeletons loaders (https://medium.com/android-dev-nation/android-skeleton-loaders-1ae979a9d8c9)

That's definitely something worth discussing internally, I've added it to the list of thing to consider for the next version. Thanks for your feedback.
