I tested different options to try to solve the problem but I couldn't find the solution.
I appreciate your help, thank you!!

Answer 1

I found the cause of the error.
It occurs if you have a newer version of the android support libraries in your project than that the java aar was builded with.
Most bindings for Intercom use the Intercom Android SDK Version 3.0.XX, which was built against API Level 25 (Support libraries 25.XX.XX), I think.
I could solve the problem by creating my own bindings for the newest version of the Intercom Android SDK which are build against API Level 27, which I happen to use in my project.
Basicaly you have 2 option:
Create your own Bindings with the new Intercom Version
Downgrade your API Level and Support Libraries to Version 25.XX.XX
I might upload my Binding of the new Intercom Android SDK to github at some point, however it might take some time until I will be able do so.
