Occasionally crash when IOS app is in background mode. #391

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Occasionally crash when IOS app is in background mode. I can see one worker 
thread in GAI library is still running and prevent the IOS put my app to sleep 
again.
Setting dryRun and removeTracker doesn't work to stop that worker thread. I 
need release function from GAI library that will dealloc the library.

Google Analytics iOS SDK version 3.02.

This is also happening to our app.  We have gotten many reports from customers 
about the app getting killed during checkout if they leave the app for more 
than a minute or two.  We are probably going to remove this library until this 
issue is fixed.

The crash report highlights the GAI thread as the culprit:

Also am seeing the exact same thing in my app on most recent 3.14, any word on 
this? May end up removing the library as well.
