How to benchmark the fps of an animation in android?

Question

It would be really cool to benchmark how many times per second an animation actually gets drawn to the screen in an android app. Is there a way to do it?

ie. I can set an animation to run over a 250ms period, but I want to benchmark how smooth it is objectively.

Answer 1

If you have a game loop running, you can calculate the framerate as follows:

FrameRate= 1000/LoopTime

Where LoopTime is the time it takes to execute an Update call and Draw call.
