Hi @icarusdust, the latest version of the library is developed using Java 11(similar to all recent RN libraries) and that seems to be causing this issue as I understand it. You may either need to use the previous version or update your project to use JDK 11. Can you please try one of these and let us know if it resolves this

[icarusdust]

Thanks for getting back @NMGuner. Tried both options, downgraded the SDK version with different Java versions, and tried to build the latest SDK version with JDK 11. I am afraid, none of them helped.

  reason: '<>' with anonymous inner classes is not supported in -source 8
    (use -source 9 or higher to enable '<>' with anonymous inner classes)

It is higher than 9, but not sure why it is considered below 9.

Anything else to check ? @NMGuner

Facing the same issue while using JDK 15, any solution for this ?

A new version is released (v2.2.1) that should resolve the issue.
