After deployment of an app to Google Play Beta I see next issue in Crashlytics (6 - 7 users are affected)
Fatal Exception: java.lang.IllegalStateException: UiAutomation not connected!
at android.app.UiAutomation.throwIfNotConnectedLocked(UiAutomation.java:971)
at android.app.UiAutomation.disconnect(UiAutomation.java:237)
at android.app.Instrumentation.finish(Instrumentation.java:222)
at android.support.test.runner.MonitoringInstrumentation.finish(MonitoringInstrumentation.java:351)

at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1960)
It seems that it's google test devices. Any ideas about fix?
It seems like nothing to worry about (don't rely on accepted answer and don't remove your tests) because crashes have been reported on creating pre-launch report for google play store where some UI automation tests were executed. If you track devices on which this error has occurred - you'll see that all paths leads to pre-launch report.
