GeoView's dispose method crashes after migrating to 100.8

[NandKishore]

We are seeing a below crash after upgrading to 100.8 ArcGIS:

This crash appears from our Activity's onDestroy() when we have called  MapView.dispose() (in turn calling the GeoView class's

RenderingThread's dispose() method)

As this exception occurs in a different thread, we are unable to catch this exception.  

Any ideas what causes this crash?

Nand Kishore‌ Have you find any solution for this ?

[MarkBaird]

Can you give me a little more background on this issue?

 - what does your app do?

 - what device are you using?

 - can you share any code?

If you take a very basic app such as this sample can you reproduce it?

[NandKishore]

We went back to ArcGIS version 100.7 to resolve this issue as 100.7 doesn't use TextureView.

Thanks.

I just had the same thing happen with 100.9.0 and in my case this was due to the fact that the MapView was not visible having in some situations been set to: mapView.setVisibility(View.GONE). If mapView.dispose() is called in this state it will crash.

The workaround is to check if it's visible before disposing:

if (mapView != null && mapView.getVisibility() == VISIBLE) {
  mapView.dispose();
}
