如何捕获BadTokenException在我的应用程序中发生的位置？

Question

note: this is not a repeated question

Hi, I have this exception in my application

Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@dff5aa2 is not valid; is your activity running?

I found a lot of questions ask about this crash and I know that it mostly happens because of showing dialog in a finished activity

the problem is I am working on a big application with a great number of custom dialogfragment s in a lot of activity, I tried to review all of it by eyes but it was very hard and as you see the logs from Crashlytics is not saying where it happens

What I am asking for: Is there is any tool or way help me to review my code and catch an error like that?
