signal 5 (SIGTRAP), code 1 (TRAP_BRKPT) relating to webview.apk
I'm receiving a handful of crash reports in my Play Console with the following title:
signal 5 (SIGTRAP), code 1 (TRAP_BRKPT)
webview.apk
and the following detail:
backtrace:
native: pc 00000000011a1ed4 /system/app/webview/webview.apk
native: pc 00000000011e01f8 /system/app/webview/webview.apk
That is it, no more information available.
What is significant is that (a) the number of crashes is very small, so my code must basically be sound, and (b) the reports are all from Android 7.0 devices.
How do I even begin to work out where the crash could be occuring? I could post some code, but it probably won't help because the vast majority of devices aren't choking, and in any case I'm just looking for a bit of insight or hints as to where to look further. I cannot reproduce this crash on any device I've tried.
There is a similar question here, also with no answer.
Answer
It's an known, un-fixable bug with the Chrome WebView on Android 7 and above. The WebView is used to display the ads whether you create one or not. It's not specific to AdMob. Don't count on this getting fixed, it's been present since 2017 and crashes are being forwarded to the Chrome team, not Admob team.
