Answer 1

My team faced a similar problem just yesterday. The solution is to update the recyclerview-animators used in your project to its newest version, 2.0.1:

compile 'jp.wasabeef:recyclerview-animators:2.0.1'

Appearantly it's a known issue as the developer has also mentioned about older versions's incompatibility with Support Library 23.0.1.

Answer 2

To use https://github.com/wasabeef/recyclerview-animators with RecyclerView follow the Setup and update the library

Gradle

If you are using a RecyclerView 23.1.0 (released Oct 2015) or higher.

dependencies {
  // jCenter
  compile 'jp.wasabeef:recyclerview-animators:2.1.0'
}

If you are using a RecyclerView 23.0.1 or below.

dependencies {
  // jCenter
  compile 'jp.wasabeef:recyclerview-animators:1.3.0'
}
