Null pointer on Mapview when activity OnResume occures

JayBowman12 — Thu, 29 Apr 2021 18:07:00 GMT

I have a mapView and I'm navigating along a route. I switch to another app then back to my navigation app the onResume fires. ArcGIS runtime is 100.11

@Override protected void onResume() { super.onResume(); if (mMapView != null) { mMapView.resume(); } }

The mMapView.resume() is executed and I get this:

Caused by: com.esri.arcgisruntime.ArcGISRuntimeException: Null pointer.: object cannot be null.

Hi,
Could you repro the problem with the following sample?
https://github.com/Esri/arcgis-runtime-samples-android/tree/main/java/navigate-route

If so, do you see it on all devices or seeing this behavior on any specific device. Also can you provide the logcat info when you get this error.

Thanks
Rama
