When I update gradle and build my project I get the error below:

There was no error with gradle 2.1.4

  • Can you show what your `values.xml` looks like? It seems like your error is most likely related to this message `error: duplicate value for resource 'attr/layout_anchorGravity' with config ''.` – Karl Oct 01 '18 at 18:08

There are two problems here

First, look through the files under your app/src/main/res/values. One of them defines a style, and uses an attribute as the parent for that style:

D:\MyAndroidApp\MyApp2\MyApp\build\intermediates\incremental\mergeWithAnalyticsDebugResources\merged.dir\values\values.xml:2143: error: invalid resource type 'attr' for parent of style.

Style's parents can only be styles. Either remove that parent completely or change it to another style.

Secondly, there seem to be two conflicting definitions of an attribute layout_anchorGravity - either in your dependencies or in your local values files. Check where this attribute is coming from and either override it or remove it completely.
