使用環信開發項目遇到錯誤提示 configure your build for VectorDrawableCompat，vectordrawablecompat

問題描述：在使用AndroidStudio開發項目時，使用環信重寫了聊天界面後，運行時app就崩掉了，查看日志報告，提示報錯如下：

根據提示，明顯是配置出現問題，找環信的客服咨詢，他們只說讓我去掉引用的v7包，可是仍然不好使。

解決方案：後來機智如我，查看環信Demo的Activity，是繼承EaseBaseActivity的，而我自己寫的Activity是繼承了AppCompatActivity，so找到問題的關鍵了，把繼承的父類改成環信自己的EaseBaseActivity就可以了。
