@vkbellis Thanks for the report! Could you please capture a bug report after this crash happens (https://developer.android.com/studio/debug/bug-report#bugreportdevice) and share it?

Hi Sean,
I just tried running another test (unsuccessfully) on the Moto E4 Plus, followed by the requested generation of a bug report, then this repeating notice:

Google Play services isn't responding
Close app
Wait
Send Feedback

Tapping: Wait, Wait, Wait, eventually was able to send an email from the Android device to myself... which still still hasn't arrived... until just now!

Hope this helps. - Kind regards, Kelly

Thanks!! From the bug report, seems like this may be the relevant error:

Looks like this is the fix for the 1st stack trace - https://stackoverflow.com/a/67900719/937715.

[vkbellis]

Issue still seems to be present in GPSTest v3.10.1 - see attached bug report.

@vkbellis Thanks for the bug report, I'll take a look

[barbeau]

That's strange, I'm still seeing the same issue with the method LocationListener.onProviderDisabled() even though it's implemented in v3.10.1. I wonder if it has something to do with using Kotlin...

We could try using LocationListenerCompat - https://b.corp.google.com/issues/190695723.

[barbeau]

@vkbellis I'm rolling out v3.10.2 now that I'm hoping will fix this. Could you please give it a try?

[barbeau]

@vkbellis Could you also please try to run the latest GnssLogger release (https://play.google.com/store/apps/details?id=com.google.android.apps.location.gps.gnsslogger) and let me know if you see the same crash there?
