Hi Chris.
I understand that you don't have this functionality. That's why this thread is called "feature request for ANR reduction". We need to trace ANR reasons in the Crashlytics console. There are high chances that quite a few ANRs happen during the ad loading process. In order to be able to prove/disprove this we need ad load start/end events. In order to identify a broken ad we need the ad id for load start event. It's not enough to have only the ad finish event: if ANR happens Crashlytics sends a log with events registered _before_ ANR happens.
Please, note that AdMob introduces an unacceptably high amount of ANRs into our project. If we won't be able to trace them down in a few weeks and go below the threshold, our management wants us to switch to the more developer-friendly solutions which are used on our other projects. We are also considering removing AdMob completely from all waterfalls. It is absolutely unacceptable that AdMob ruins our application. I know that you guys didn't move a finger to address this issue -- lots of reports were, lots of complaints all over the internet -- for more than two years already and even made things worse every few months, so, please, just add minor helpers to allow us to fix at least some of the issues ourselves.
