使用环信开发项目遇到错误提示 configure your build for VectorDrawableCompat

问题描述：在使用AndroidStudio开发项目时，使用环信重写了聊天界面后，运行时app就崩掉了，查看日志报告，提示报错如下：

根据提示，明显是配置出现问题，找环信的客服咨询，他们只说让我去掉引用的v7包，可是仍然不好使。

解决方案：后来机智如我，查看环信Demo的Activity，是继承EaseBaseActivity的，而我自己写的Activity是继承了AppCompatActivity，so找到问题的关键了，把继承的父类改成环信自己的EaseBaseActivity就可以了。
