Got error IllegalStateException: already recycled once at ViewGroup.java class?

Question

Why IllegalStateException occur? (already recycled once) This exception is coming from ViewGroup.java class and is unable to resolve that error. And this crash did not occur in my device but the In users phone app crashes with a given exception.

ViewGroup.java line 9606

Answer 1

did you debug ViewGroup.java ? putting debugger point in line 9606 ? Would be better if you can post from what you are doing likewise. so the others can get some insight about giving you an answer! thanks
