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

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

to 

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.

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.
