Where to find '/data/anr/traces.txt'?

Hello,

I'm testing a Xamarin.Forms app. When I get to the third page of my app, the app crashes and the console in Visual Studio reports to me:

12-15 10:39:28.265 I/art (14576): Wrote stack traces to '/data/anr/traces.txt'

I searched my phones files but I am not able to find this file, so my question is: Where can I find it?

Thanks inn advance.
