Android build failed when enabling for Distribution UE4.16.3

My android build fails when checking for distribution option.

But from the log i suspect it has something to do with proguard settings.
Please check both the log and the proguard attached. I appreciate any kind of help.


Can anyone help me with this problem?

It’s literally the last thing i need to do before starting my beta phase.

I was able to solve the problem using the answer and video provided in the following link

Specially the part regarding updating the proguard version.
