I have heard a number of reports of this problem that were caused by apps using libraries that run a service in a separate process like Google Cloud Messaging and Nokia Here Maps. You may not even be aware that you are using a library that does this.

A fix for this was put in #479 and is available for testing in this binary release:

https://github.com/AltBeacon/android-beacon-library/releases/tag/2.11-beta1

@jmvines, please try that release and let me know if it solves your problem.

Regards.

This fix described has been released in 2.11. Please reopen if that does not solve the problem.
