Error prompt configure your build for vectordrawablecompat when using Huanxin development project

Problem Description: when using Android studio to develop a project, after rewriting the chat interface with Huanxin, the app will collapse at runtime. Check the log report, and the prompt error is as follows:

According to the prompt, there was obviously a problem with the configuration. I went to the customer service of Huanxin for consultation. They only told me to remove the referenced V7 package, but it was still difficult to use.

Solution: later, I was as smart as me. When I checked the activity of Huanxin demo, it inherited easebaseaactivity, and the activity I wrote inherited appcompatactivity. So I found the key to the problem and changed the inherited parent class to Huanxin's own easebaseaactivity.
