The problem is not ObjectAnimator, but rather that your application is simply doing too much on every frame of the animation. Specifically, you are animating layout params and requesting layout on every frame. Layout is powerful and useful... but can be quite expensive in any but the most trivial of view hierarchies. It's important to avoid expensive operations per-frame during animations, and layout falls into that "expensive" category. Sliding things around is fine (translationX/Y), fading things in/out is good (alpha), but actually laying things out on every frame? Just say no.
