Can't set up Zebra's scanner

Hi everyone! I'm having several difficulties to set up TC56's scanner. In both cases, when I do scanner.enable() or the app closes  in runtime with this message in Logcat:

Check failed: called != nullptr int java.lang.Enum.ordinal() com.symbol.emdk.EMDKManager$FEATURE_TYPE[] virtual 15're

I've been trying different solution and I found this post:
where developer had a similar problem. I can use the app correctly if I use debug on it. However, I tried the solution that was marked and nothing happened.

Has anyone faced a similar problem?

Thanks in regards
