I'm pretty sure that this problem is not related to the the library.

The attribute has already been defined in values.xml. This should probably be related to AppCompat libraries.

See, values.xml not exists in project https://github.com/inmite/android-validation-komensky/tree/master/demo/src/main/res/values
