java.util.NoSuchElementException after app is running for 2-4 days #139

Open bromeostasis opened 8 years ago

bromeostasis commented 8 years ago

After we leave our app in the background for a few days with this plugin running, it crashes in the background with no explanation. After writing a custom java exception handler, I finally was able to grab the following stacktrace:

The issue seems to mostly happen while moving around in the car (presumably entering/exiting a lot of geofences). As mentioned, it takes a long time to reproduce, so we don't have a ton of info on root causes.

I haven't had much time to look at this/analyze today, but I was wondering if anyone else has seen this issue or could provide some insight into why this might happen. I'm happy to provide any more details about cause/testing/etc.

Thanks in advance!

Got another different error with a build in the background for a few days:

I have same error as first stack trace.

@jyyblue1987 we've since moved to https://github.com/transistorsoft/cordova-background-geolocation , which does not have as many problems in the background, but we do pay for Android use.
