ANR on mostly Motorola devices with Android 7 and 8

Reported by car...@instantbits.com, Jul 4 
THIS TEMPLATE IS FOR FILING BUGS ON THE ANDROID SYSTEM WEBVIEW. GENERAL WEB BUGS SHOULD BE FILED USING A DIFFERENT TEMPLATE!

Device name: Seems to be mostly motorola devices, list included on screenshot.

Android version: 7 and 8

WebView version (from system settings -> Apps -> Android System WebView): Don't know. 

Application: Web Video Caster

Application version: 3.2.0.2 and 3.2.1

URLs (if applicable): Don't know

Steps to reproduce: Don't know how

I'm getting this ANR on the Play Store console, it has never happened to me but I don't have any of the devices on the screenshot.

hmm, it would be helpful to have some scenario/steps to reproduce, i.e. when does this happen? after something is cast in the "Web Video Caster" app?

Comment 3 by car...@instantbits.com, Jul 9 

I've never actually seen this myself, nor has a user reported it. I see it only on the Play Store console. That being said, after casting, Web Video Caster moves on a different screen and the WebView is paused. So it shouldn't cause an ANR, should it? unless the pausing of the WebView is doing it but that is required not only to save battery but because YouTube does not permit third party apps to enable background playback.

As per comment #1, there are no possible steps to reproduce and could not find suspect from logs provided in comment#0. So, requesting dev to look into this issue.

@boliu: Could you please look into this issue and help us in assigning to the right owner.

Thanks!

ANR in webview without steps to actually reproduce it is not actionable. See my comments in  crbug.com/857459

One thing I forgot to mention is that I do also have ads, most are native, but I have an occasional banner and interstitial, so these crashes could come from there as well.
