This looks to be an OOM/ANR from a quick look. I can reproduce on a Pixel 3.

I've reproduced bug 1680999 on my phone and it is indeed an out-of-memory crash. On Android we cannot intercept OOM crashes because they're indistinguishable from regular application shutdowns (Android always kills applications, they never shut down cleanly like a desktop one would do). As such we can't intercept them and generate a regular crash report. I'm closing this bug as INVALID because of this.

It might be possible to record the event and send a crash ping instead but we'd have to investigate that.
