Crash on Android from CameraDevice.java(line 297)

Question

I started receiving crash report with this error and call stack : 

Fatal Exception: java.lang.RuntimeException

Unable to pause activity {com.editionsalaska.ra/com.editionsalaska.ra.ARScannerActivity}: java.lang.RuntimeException: getParameters failed (empty parameters)

com.editionsalaska.ra.easyar.GLView.onPause (GLView.java:101)
com.editionsalaska.ra.ARScannerActivity.onPause (ARScannerActivity.java:146)

Any ideas why? 

Answer 1

Seems to be happening only on Samsung devices... 66% of the time in Android 8, and 63% of the time when app is in background state.

Answer 2

I experience the same thing when I try to pause the engine. Help would be appreciated!
