Hello, I've experienced few crashes of Estimote SDK (v0.12.0) on Nexus 5X running Android Nougat. Here is the stack trace:

Fatal Exception: java.util.ConcurrentModificationException at java.util.ArrayList$Itr.next(ArrayList.java:831) at com.estimote.sdk.cloud.internal.AnalyticsManager.generateEvents(AnalyticsManager.java:137) at com.estimote.sdk.service.BeaconService.invokeCallbacks(BeaconService.java:681) at com.estimote.sdk.service.BeaconService.access$5000(BeaconService.java:93) at com.estimote.sdk.service.BeaconService$7.onScanCycleCompleted(BeaconService.java:1072) at com.estimote.sdk.service.BeaconService$6.run(BeaconService.java:928) at android.os.Handler.handleCallback(Handler.java:751) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:154) at android.os.HandlerThread.run(HandlerThread.java:61)

Crashes happened few times while app was running in background.

Hello @bstokrocki

Thanks for reporting that - we cannot reproduce that for now, but we will add more protection for this case. Will get you informed as soon as possible.

Edit: If this is really affecting your work, you can disable Analytics for now in EstimoteSDK class:

enableMonitoringAnalytics(false);
enableRangingAnalytics(false);
