Libgdx Animation run loop only twice

So I'm trying to stop an animation after running twice. I am playing the animation by setting 

Animation blink = new Animation(BLINK_TIME, frames); // parameters are my fields

This is how i get my current frame: 

   if(animate){
      stateTime += Gdx.graphics.getDeltaTime(); //stateTime was initialized to 0
      currentFrame.setRegion(blink.getKeyFrame(stateTime, true)); 
}
else 
   currentFrame.setRegion(defaultRegion);  // again, my own field!

Everything works fine uptill here when the animate field is true. Now I want to stop the animation, this is what I do for it:

if(blink.isAnimationFinished(stateTime)){
        blinkTimes++;
        if(blinkTimes>=2)
            animate = false;
    }

The problem is, isAnimationFinished(stateTime) never gets called. I guess it has to do something with looping animation. Can someone please point me in the right direction? Thanks!

Found the Problem!

isAnimationFinished(stateTime) does not work when animation is being played in the loop. So, I had to play it in Animation.Normal mode and use false in blink.getKeyFrame(stateTime, false) telling the Animation class to run it in non-loop mode!

Everything seems ok. I think you have initialized

stateTime = 0;

inside the render method or update method where firstly its value = 0 and then you add deltaTime to it.. In the end it never reaches to position where animation gets finished. I think you should log the value of stateTime when your 

if(animate) // log what is your stateTime

And 1 more thing

  if(blink.isAnimationFinished(stateTime)){
    blinkTimes++;
     stateTime = 0 ; //----------- because your animation should start from begining else it will complete 2 cycles in no time.
    if(blinkTimes>=2)
        animate = false;
}

I hope this helps.. and if i am not getting your question properly just let me know.
