String mode policy logs now showing anything related to my code

Question

I recently started receiving constant ANR messages in my app. I am unable to find out what's causing them. I enabled StrictModePolicty but the logs (shown below) don't indicate anything related to my code. Can someone help me understand what's going on here?
