Hi, im new at using this library and its great so i tried to add appcompat for alerts but after doing this i get this error:

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 27.1.1. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:support-media-compat:27.1.1

Already solved forcing: implementation 'com.android.support:support-media-compat:28.0.0' implementation 'com.android.support:support-v4:28.0.0'

But i send this because read on SO that this could cause problems in the future so maybe you can update this. Great job guys.
