System.NotSupportedException while working with MapView

[SougataBasu]

Error : System.NotSupportedException: Could not activate JNI Handle 0x7fca1a7480 (key_handle 0x2ad6405) of Java type 'Esri/ArcGISRuntime/UI/MapView' as managed type 'Esri.ArcGISRuntime.UI.MapView'.

I am facing this error while working with ESRI map in a existing project.

Below is the package information -

package id="Esri.ArcGISRuntime.Xamarin.Android" version="100.2.0" targetFramework="monoandroid60"

This error exists in version="100.2.1" also.

I have followed all replies of this thread :  System.NotSupportedException: Could not activate JNI Handle 0x7fca1a7480 (key_handle 0x2ad6405) of ... 

But that didn't work for me.

Please reply with some solution ASAP.
