Application crashes when trying to get KML nodes near a specified point (Android Runtime SDK 10.2.9)

MohammedAbdul_Azeez — Sun, 12 Dec 2021 01:15:42 GMT

For our application we are using ArcGIS Runtime SDK for Android 10.2.9.

In the application, we are able to add KML using KmlLayer.
But when we try get the KmlNode[], near a tapped point,
using the provided getKmlNodes(double x, double y, int tolerance) method,
the application randomly crashes.
We tried using try/catch to catch the error and also tried changing tolerance values.

Also, we have tested in many devices and with different KML files as well.

In Logcat we are getting the following error
"A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0xe9 in tid 25802 (om.ex.test), pid 25802 (com.ex.test)"

The backtrace seems to point to the Esri_runtimecore.::KML C++ class.

Is there any workaround for this error?

10.2.9 is a very old release which is no longer supported or in development.

The current release of ArcGIS Runtime is 100.9. Have you tried your layer in this version?

If you want to try it out, there is a github repository with lots of samples showing how to implement various use-cases. This sample may be of interest to you:
