ArcGIS Map Error: Unable to create instance of class com.esri.arcgisruntime.internal.io.b

ChristopheVan_Baalen

Hi!
I'm having some customers complaining about the maps not loading after updating to the latest version of our app. (It's an Expo react-native app with a custom implementation for Android and iOS)

The only changes we've done is updating

com.esri.arcgisruntime:arcgis-android:100.15.6

com.esri.arcgisruntime:arcgis-android:100.15.7

This only happens on the customers maps, which have a lot of data and moving stuff, but works great on my smaller test map.

In development I see this error:
ArcGIS Map Error: Unable to create instance of class com.esri.arcgisruntime.internal.io.b.
Registering an InstanceCreator or a TypeAdapter for this type, or adding a no-args constructor may fix this problem

I can't find anything related to this issue, maybe anyone of you have some idea on whats going on?

@ChristopheVan_Baalen - can you check the gson dependency your app is using. The ArcGIS Runtime SDK for Android 100.15.7 depends on gson 2.9.0. If your application depends on a newer version of gson, this might be the cause of this issue.

ChristopheVan_Baalen

I tested adding a specific implementation dependency for gson (implementation 'com.google.code.gson:gson:2.9.0') to our custom ArcGIS wrapper for our expo/react-native app, but with no success. Still the same issue.

Some more information:
The error pops up twice: Once in Portal.addDoneLoadingListener when it’s LoadStatus.FAILED_TO_LOAD, but also for the ArcGISMap.addDoneLoadingListener with the same load status.

Here is one map that is working correctly: https://learngis.maps.arcgis.com/home/webmap/viewer.html?webmap=3476f0e5637c481b89eafd18b6620c79

And here is one of the maps which fails: https://cypsol.maps.arcgis.com/apps/mapviewer/index.html?webmap=b7c4b33f094140c18522df1c233ad184

I created a simple test app for reproducing this issue:
