不熟悉Android工作室，因为我一直遇到问题。我的应用程序运行良好，直到与云后端有关的事情，我从未触及过这个错误让我无法继续：
warning: [options] bootstrap class path not set in conjunction with -source 1.7
C:\Users\JC\Projects\ca.usimage.resto.RestonetActivity\backend\build\generated-source\endpoints\java\com\example\jean\myapplication\backend\myApi\MyApi.java:279: error: method does not override or implement a method from a supertype

^

2 errors

我升级到Android Studio 3，更新了我能做的一切，甚至从一年前的github备份回溯到一个新项目，我仍然得到错误。
出了什么问题？
关于重新安装Android Studio，或切换回Eclipse（yuck）
