  <p>On getting dependency tree, I found that there is nothing wrong with animated vector drawables but facebook's latest sdk has previous version of support-v4 custom tab. I tried excluding with exclude group command but its not working. Here is my dependency tree:</p>

  <p>I want to use latest appcompat library as I want to support Oreo. Can someone guide me on this? Also, isn't this facebook's fault to use older dependency for custom tabs? Thank you very much for your time and assistance in this matter.</p>
